here is a cell the basic unit of all
0:20
living tissue in most human cells there
0:24
is a structure called the nucleus the
0:28
nucleus contains the genome in humans
0:31
the genome is split between 23 pairs of
0:34
chromosomes each chromosome contains a
0:39
long strand of DNA tightly packaged
0:41
around proteins called histones within
0:47
the DNA are sections called genes these
0:51
genes contain the instructions for
0:53
making proteins when a gene is switched
0:58
on an enzyme called RNA polymerase
1:00
attaches to the start of the gene it
1:04
moves along the DNA making a strand of
1:07
messenger RNA out of free bases in the
1:10
nucleus the DNA code determines the
1:14
order in which the free bases are added
1:16
to the messenger RNA this process is
1:20
called transcription
1:26
before the messenger RNA can be used as
1:29
a template for the production of
1:31
proteins it needs to be processed this
1:35
involves removing and adding sections of
1:37
RNA the messenger RNA then moves out of
1:43
the nucleus into the cytoplasm protein
1:52
factories in the cytoplasm called
1:54
ribosomes bind to the messenger RNA the
1:59
ribosome reads the code in the messenger
2:01
RNA to produce a chain made up of amino
2:04
acids there are 20 different types of
2:08
amino acid transfer RNA molecules carry
2:12
the amino acids to the ribosome the
2:17
messenger RNA is read 3 bases at a time
2:20
as each triplet is read a transfer RNA
2:24
delivers the corresponding amino acid
2:29
this is added to a growing chain of
2:32
amino acids once the last amino acid has
2:39
been added the chain folds into a
2:42
complex 3d shape to form the protein
2:53

2:58
protein synthesis translation inside the
3:04
body the process of translation occurs
3:06
within every single cell each cell has a
3:10
nucleus after transcription mRNAs move
3:16
out of the nucleus and enter the
3:18
cytoplasm this mRNA strand acts as a
3:24
template for protein synthesis present
3:28
in the cytoplasm is an enzyme amino acyl
3:31
tRNA synthetase the enzyme macro
3:35
molecule has two binding sites one site
3:38
recognizes the amino acid methionine
3:42
this is followed by the binding of the
3:45
ATP molecule and release of
3:49
pyrophosphate resulting in activation of
3:54
amino acid finally the tRNA and the
4:01
activated amino acid bind together this
4:08
amino acyl ated tRNA is known as met
4:12
tRNA and is released from the enzyme
4:16
this marks the commencement of first
4:18
stage of protein synthesis the
4:20
initiation stage during the eighth
4:25
initiation stage a small subunit of a
4:28
ribosome binds to the mRNA strand the
4:34
mRNA strand is made up of codons which
4:37
are sequences of 3 bases then the
4:41
ribosome subunit moves along the mRNA in
4:44
five prime to three prime direction
4:47
until it recognizes the Aug codon or the
4:51
initiation codon
4:53
at this point net tRNA possessing the
4:58
anticodon UAC pairs up with the Aug
5:01
codon of the M RNA then a large subunit
5:07
of ribosome combines with a small
5:09
ribosomal subunits the lab subunit shows
5:14
three sides the acceptor site or the a
5:18
site v dial site or the P site the exit
5:23
site or the e site this whole unit forms
5:27
the initiation complex this is followed
5:31
by the elongation stage during this
5:36
stage another tRNA carrying molecule of
5:39
an amino acid approaches the M RNA
5:42
ribosome complex and fits in the a site
5:46
then a bond is formed between methionine
5:49
and the amino acid molecule on the tRNA
5:53
as a result met tRNA becomes d isolated
5:58
the ribosome then advances a distance of
6:01
one codon and the D isolated tRNA shifts
6:05
to the east side from where it
6:06
dissociates meanwhile another tRNA
6:12
carrying an amino acid molecule attaches
6:15
to the a site this is followed by the
6:20
binding of the amino acid molecules
6:23
[Music]
6:25
repetition of this process leads to the
6:28
formation of an amino acid chain
6:31
this event is called elongation finally
6:40
when the UAG codon or the stop codon
6:43
reaches the a site elongation is
6:45
terminated termination is the last stage
6:49
of protein synthesis the chain of amino
6:53
acid molecules is released from the
6:56
ribosome this released amino acid chain
7:00
is the protein and this part of protein
7:03
synthesis is known as translation then
7:09
the tRNA detaches from the mRNA ribosome
7:15
detaches and dissociates into its small
7:18
and large subunits
7:23
summary protein synthesis shows that the
7:27
first stage involves the binding of met
7:29
tRNA to M RNA and the small subunit of
7:33
the ribosome the larger subunit of
7:36
ribosome then combines with a small
7:39
subunit second stage is the elongation
7:44
stage in this stage the incoming amino
7:50
acyl tRNA fits in the a site then a bond
7:55
is formed between methionine and the
7:57
amino acid molecule on the tRNA the
8:03
process is repeated until a chain of
8:05
amino acid molecules is formed the last
8:10
stage of protein synthesis is the
8:12
termination stage when the ribosome
8:15
reaches the stop codon you AG elongation
8:19
stops and the newly formed a minor acid
8:21
chain which is the protein macro
8:23
molecule detaches from the ribosome
8:31
subsequently ribosomal subunits along
8:34
with the tRNA dissociate from the M RNA

8:43
in order for our bodies to function we
8:46
need to supply them with a variety of
8:48
nutrients we get from our diet
8:51
our bodies cannot use the food as it is
8:54
when it enters our digestive system the
8:56
process of chemical digestion uses
8:59
different proteins and enzymes to break
9:02
down the food particles into usable
9:04
nutrients our cells can absorb
9:07
and where are the instructions to
9:09
manufacture these and all the different
9:11
types of proteins we need to stay alive
9:13
the instructions to make proteins are
9:16
contained in our DNA DNA contains genes
9:20
a gene is a continuous string of
9:23
nucleotides containing a region that
9:25
codes for an RNA molecule this region
9:29
begins with a promoter and ends in a
9:32
terminator genes also contain regulatory
9:35
sequences that can be found near the
9:37
promoter or at a more distant location
9:40
for some genes the encoded RNA is used
9:44
to synthesize a protein in a process
9:46
called gene expression for these genes
9:49
expression can be divided into two
9:52
processes transcription and translation
9:55
in eukaryotic cells transcription occurs
9:59
in the nucleus where DNA is used as a
10:03
template to make messenger RNA then in
10:06
translation which occurs in the
10:08
cytoplasm of the cell
10:10
the information contained in the
10:12
messenger RNA is used to make a
10:15
polypeptide
10:17
during transcription the DNA in the gene
10:20
is used as a template to make a
10:21
messenger RNA strand with the help of
10:24
the enzyme RNA polymerase this process
10:28
occurs in three stages initiation
10:31
elongation and termination during
10:35
initiation the promoter region of the
10:38
gene functions as a recognition site for
10:40
RNA polymerase to bind this is where the
10:44
majority of gene expression is
10:46
controlled by either permitting or
10:48
blocking access to this site by the RNA
10:51
polymerase binding causes the DNA double
10:54
helix to unwind and open then during
10:58
elongation the RNA polymerase slides
11:01
along the template DNA strand
11:04
as the complementary bases pair up the
11:07
RNA polymerase links nucleotides to the
11:10
3 prime end of the growing RNA molecule
11:15
once the RNA polymerase reaches the
11:18
terminator portion of the gene the
11:20
messenger RNA transcript is complete and
11:23
the RNA polymerase the DNA strand and
11:26
the messenger RNA transcript dissociate
11:29
from each other
11:32
the strand of messenger RNA that is made
11:35
during transcription includes regions
11:37
called
11:38
exons that code for a protein and
11:40
non-coding sections called introns in
11:44
order for the messenger RNA to be used
11:46
in translation the non-coding introns
11:49
need to be removed and modifications
11:52
such as a five prime cap and a 3 prime
11:55
poly a tail are added this process is
12:00
called introns splicing and is performed
12:03
by a complex made up of proteins and RNA
12:06
called a spliceosome
12:09
this complex removes the intron segments
12:12
and joins the adjacent exons to produce
12:14
a mature messenger RNA strand that can
12:17
leave the nucleus through a nuclear pore
12:19
and enter the cytoplasm to begin
12:22
translation
12:25
how is the information in the mature
12:28
messenger RNA strand translated into a
12:30
protein the nitrogenous bases are
12:33
grouped into three letter codes called
12:35
codons
12:38
the genetic code includes 64 codons most
12:42
codons code for specific amino acids
12:46
there are four special codons one that
12:49
codes for start and three that code for
12:51
stop
12:53
translation begins with the messenger
12:56
RNA strand binding to the small
12:58
ribosomal subunit upstream of the start
13:01
codon each amino acid is brought to the
13:04
ribosome by a specific transfer RNA
13:07
molecule the type of amino acid is
13:11
determined by the anticodon sequence of
13:13
the transfer RNA
13:16
complementary base pairing occurs
13:18
between the codon of the messenger RNA
13:21
and the anticodon of the transfer RNA
13:26
after the initiator transfer RNA
13:29
molecule binds to the start codon the
13:31
large ribosomal subunit binds to form
13:34
the translation complex and initiation
13:37
is complete
13:39
in the large ribosomal subunit there are
13:42
three distinct regions called the e P
13:46
and a sites
13:49
during elongation individual amino acids
13:52
are brought to the messenger RNA strand
13:55
by a transfer RNA molecule through
13:58
complementary base pairing of the codons
14:00
and anticodons each Eddie codon of a
14:04
transfer RNA molecule corresponds to a
14:07
particular amino acid
14:11
a charged transfer RNA molecule binds to
14:14
the a site and a peptide bond forms
14:17
between its amino acid and the one
14:19
attached to the transfer RNA molecule at
14:21
the P site
14:24
the complex slides down one codon to the
14:27
right where the now uncharged transfer
14:30
RNA molecule exits from the e site and
14:32
the a site is open to accept the next
14:35
transfer RNA molecule
14:39
elongation will continue until a stop
14:41
codon is reached
14:47
a release factor binds to the a site at
14:50
a stop codon and the polypeptide is
14:52
released from the transfer RNA in the P
14:55
site the entire complex dissociates and
14:59
can reassemble to begin the process
15:01
again at initiation the purpose of
15:04
translation is to produce polypeptides
15:07
quickly and accurately
15:09
after dissociation the polypeptide may
15:13
need to be modified before it is ready
15:15
to function
15:17
modifications take place in different
15:19
organelles for different proteins
15:22
in order for a digestive enzyme to be
15:25
secreted into the stomach or intestines
15:27
the polypeptide is translated into the
15:30
endoplasmic reticulum
15:32
modified as it passes through the Golgi
15:35
then secreted using a vesicle through
15:38
the plasma membrane of the cell into the
15:41
lumen of the digestive tract
15:45
proteins are needed for most
15:47
physiological functions of the body to
15:49
occur properly such as breaking down
15:52
food particles in digestion and the
15:54
processes of transcription and
15:56
translation make the production of
15:58
proteins possible
video 4.
16:04
the job of this mRNA is to carry the
16:07
genes message from the DNA out of the
16:10
nucleus to a ribosome for production of
16:13
the particular protein that this gene
16:15
codes for there can be several million
16:19
ribosomes in a typical eukaryotic cell
16:24
these complex catalytic machines use the
16:27
mRNA copy of the genetic information to
16:30
assemble amino acid building blocks into
16:32
the three-dimensional proteins that are
16:34
essential for life let's see how it
16:38
works the ribosome is composed of one
16:42
large and one small subunit that
16:44
assemble around the messenger RNA which
16:47
then passes through the ribosome like a
16:50
computer tape
16:53
the amino acid building blocks that's
16:56
the small glowing red molecules are
16:58
carried into the ribosome attached to
17:01
specific transfer RNAs that's the larger
17:05
green molecules also referred to as tRNA
17:09
the small subunit of the ribosome
17:12
positions the mRNA so that it can be
17:15
read in groups of three letters known as
17:17
a codon each codon on the MRNA matches a
17:22
corresponding anticodon on the base of a
17:25
transfer RNA molecule the larger subunit
17:30
of the ribosome removes each amino acid
17:32
and joins it onto the growing protein
17:35
chain as the mRNA is ratcheted through
17:41
the ribosome the mRNA sequence is
17:44
translated into an amino acid sequence
17:48
there are three locations inside the
17:51
ribosome designated the a site the P
17:55
site and the e site the addition of each
18:01
amino acid is a three step cycle first
18:05
the tRNA enters the ribosome at the a
18:08
site and is tested for a codon anticodon
18:11
match with the mRNA next provided there
18:17
is a correct match the tRNA is shifted
18:20
to the P site and the amino acid it
18:22
carries is added to the end of the amino
18:24
acid chain the mRNA is also ratcheted on
18:29
three nucleotides or one codon thirdly
18:34
the spent tRNA is moved to the east side
18:37
and then ejected from the ribosome to be
18:39
recycled as the protein synthesis
18:44
proceeds the finished chain emerges from
18:47
the ribosome it folds up into a precise
18:50
shape determined by the exact order of
18:52
amino acids thus the central dogma
18:56
explains how the four-letter DNA code is
18:58
quite literally turned into flesh and
19:01
blood

I always find the comments on videos like these fascinating. These are all of the same diagrams that were in Freshmen Biology textbooks I used in high school, just animated. I watch them now as an adult and think they're nothing special, but so many people comment on how seeing it in motion makes all the difference in being able to understand and engage with it. I've always been the same way, but about mathematical concepts - I can look at numbers on a page and it's all gibberish until I see the concepts applied to a live example, but some people can easily visualize complex math concepts purely in their mind without effort.
It's truly incredible how differently people's minds work!

Some 40 years ago I had a talk with a biochemist. We did not talk about protein synthesis. We talked and the capabilities of nature and humans. The question came up What did humans invent that was not invented by nature already. She mentioned the zipper.
Here we see that the zipper in a much more complicated way was invented by nature some billion years, of course for different purpose.
This video contains very good animations. It does not expain everything, for example, how the cell is informed that it has to produce a certain protein.
Overall, this video is information and education at a high level.

Explained so even a mechanical engineer understands it! The biological programming is just mind blowing, not to mention the machines the programs are building. That the failure rate (illnesses) are not more frequent also is just fantastic. Well done 🤙

This is insane.
20 years ago, when I was in school, chemistry and biology were such weird and difficult to understand subjects.
But today, with the knowledge, plus the possibility of visual examples and explanations, everything is much more clear, and easier to grasp.
Now I am interested in botany and Plant tissue culture. These types of videos help a lot.
The human body is also really interesting to learn about this way.

A million thanks from the bottom of my heart for all who worked behind every tiny bit of this topic. starting from the amazing geniuses who worked it in thier heads to the ones who spent thier time creating a visual representation of the discovery and finally the ones who decided to put it all together and share it for all who have access to INTERNET !!
If only I watched it during my college days!!!!
Well better late than never !!
Once again..

Had there been such animated videos 35 yrs back I would have been a super scientist 😊 Sadly, I never had these and every time my teachers walked into a classroom to teach they either spit from a textbook or bluntly pretend to outsmart us, not knowing what they are teaching /talking! All I knew was they made most of us yawn in class. And to make it worse 90% of the biology classes were after lunch which is the time we are in food coma. Importance were given not in understanding but writing pages after pages and that too with color diagrams like you should be a super good student who can be all in all! OMG if those diagrams did not meet up to their expectations I am a dead rat. Old days yet fun to recall them now!!! Anyways, glad to know at least my kids will benefit today and I have to admit I am understanding my high school subjects more clearly now when I am watching these and teaching my kids including English grammar!!! adjective, adverb, pronoun, noun...

The fourth video... My AP biology teacher in high school showed us this in class and it was so fascinating and helpful. Now I'm in college taking Anatomy & Physiology 1 and studying for my protein synthesis quiz. I try not to remember much of high school, but I remember very distinctly learning about DNA and RNA in her class and all the worksheets she gave us to help us grasp the concepts. I'm super thankful for that now! Revisiting these topics has been a lot easier

Phenomenal explanation!! Everything was explained so clear with the added repetition.
It’s bothers me a lot that all of this happens at a molecular level and our body, cells, and DNA has all it needs to help us live.
But what was going thru my mind was this process resembles how computer science works. A step-by-step process that looks for activation/termination blocks. The codon, tRNA, Ribosomal portion blew my mind. (The translation stage)

Very nice animation! (Detail: The aa should be attached to the 3'-end of the t-RNA, not the 5'-end.)
