In the past 20 years, great progress has been made in understanding how these molecules combine and interact to form a living creature. … 77 Comments rongmaw lin Add a comment... @jessefranklin-peiper7366 2 years ago glad that there are professors like this out there, not just pumping out information, but rather taking their time to be sure their students understand the material. So patient! 35 Reply 2 replies @wackymontederamos 3 years ago This lecture made my life so much less boring. I worked as a household helper here in Singapore, all the house chores is choking me to death until I become interested into biology. Now i can cook, clean and iron so much better while listening to this lecture. 82 Reply 10 replies @tylermarshall7894 3 years ago (edited) What a badass lecture. Great work, cheers and be well! 9 Reply @jjordanbaird 2 years ago The question answered at 14:18 is excellent. It’s cool that you can find lectures and talks like this on the Tube 3 Reply @marksilver1573 1 year ago Such a complicated structure couldn't just happen by chance, nature itself is pure intelligence, and it boggles the mind! 2 Reply 1 reply @alanlee5541 3 years ago Excellent presentation which explains complex problems in a simple way. The coherence of the whole talk is so good that I enjoyed every second of the talk. Thank you! 12 Reply @rodneyspence7441 1 year ago I’ve been watching the Ken Burns documentary called “Cancer - The Emperor of All Maladies” in which they say most types of cancer involve mutations on 50-100 different genes whereas at first they thought it only involved a few. And even for those types that do just involve a few genes the cancer will keep mutating to resist the drugs. I hope some of the young people here keep learning about the cell biology so that this nightmare of a disease can be defeated. Thanks for teaching this important information in an understandable way! 3 Reply @RollingTree2 1 year ago (edited) Excellent! Explanations laying out in orderly, contextually thorough fashion what physically/visually happens, and why, via layman descriptions, before adding terminology. Rare. So often, teaching begins with, and emphasizes, terminology and abstractions, and fails to clearly link processes. Thank you! 3 Reply 1 reply @glendaoliveira5342 2 years ago Thank you for the awesome lecture! I'm a Ph.D. student, with chemistry as a background, adventuring myself in the biochemistry field. This lecture literally changed my way of understanding the basic concepts! 6 Reply 1 reply @yanag3246 3 years ago Best lecture ever! 8 Reply @markoconnell804 1 year ago So the code to make the protein which it binds to on the DNA to start is from the DNA to begin with. This is why the topoisomerase so important so a factor can get to the binding spot it is programmed for on a molecular level. Brilliant method. Thank you to whomever discovered this. Reply @Not-ip1hn 1 year ago A profound lesson on the introductory of Molecular biology, the fundamentals are truly astonishing you made a rather complex lesson turn into a simple explanation of the functions of cells to a whole new level. Reply @N3Rd32 2 years ago Very informative right off the bat. The slides really helped along with the presentation. Thank you for taking the time to create these videos and inform the public on such interesting and important subjects. 2 Reply @lugus9261 2 years ago 1:22:35 this is an interesting question because "purpose" and "function" are words we see all the time in biology in explanations for why something is the way it is, but you don't see that in other sciences as often. A geologist isn't going to tell you purpose or function of why a rock exists, just how 1 Reply @kainajones9393 1 year ago (edited) Great lesson. Would be good if your cursor were a bit more prominent . Hard to know where your pointing sometimes Reply @robertad5623 3 years ago Thank you so much for sharing! 3 Reply @zaidgamer2794 2 years ago You are amazing what a very informative lecture 1 Reply @ezzovonachalm9815 1 year ago could I have had the opportunity to see this very presentation as I was a medicine student .....!!! Reply @maharlikawarrior6625 2 years ago Topic is well-explained...thank you this video Reply @mikoplays 1 year ago Some of the questions from the audience are interesting. Reply @markoconnell804 1 year ago That extra code on the end I would guess is for the purpose of repair the code should it be degraded enough. I could be wrong certainly. Hopefully we will discover what it does later on. Reply @michasosnowski5918 1 year ago Cathalythic reactions are fascinating to me. Mln per second? It blows my mind. Its like a spider waiting on his web, so that fly would hit the web, and then its an instant hit with poison. Inside the cell, there are billions of flies propably, and the spider is much faster. Boom, and the next one. Boom, next one. On and on. Reply @_neophyte 1 year ago (edited) 33:00 this is so fascinating. it looks like machine code, like binary code (obiously it's not truly "binary" but you get the point). Our bodies are truly just machines, the most marvellous machines to ever exist. I'm going to start my degree in biomedical engineering soon because of the fascination i have for nature and the desire to contribute to people's health using technology. Reply @amosochiengowenda5466 5 months ago Great Reply @LarsLarsen77 1 year ago Who is older? The students? Or the professor? I watched this at 1.75x and it was still too slow. Reply @Ronald-xp7ry 5 months ago It seems to me that there are forces that are determinated by the structutrees of the cell. All the forces that make molecles moves are determinating tho the objective of the celular organels objective. Reply @ShellsPink 1 year ago Mmm this put me to sleep!! Thank You!! 1 Reply 1 reply @markoconnell804 1 year ago The DNA also reads backwards too. Reply @ShellsPink 1 year ago Here's a question: How do Fluoroquinolones work and how do they affect/damage DNA?? Reply @luaosiwale 2 years ago whats the relationship in Biochemistry, Molecular Biology and Genetics Reply @markoconnell804 1 year ago How does the binding factor know the correct spot to bind to the DNA? Why that spot versus any and every other spot on the DNA of the bacteria trying to get the sugar molecule? Reply @rodneyspence7441 1 year ago (edited) Hello, I’m a retired NASA aerospace engineer with no real background in cell biology, but I’m just dumbfounded by the apparent design I see here with all these intricate chemical mechanisms at work. I was thinking about the origin of the first living cell on earth. If you need a large macromolecule like a ribosome to build other protein molecules, it raises the question of the origin of the first ribosome and the origin of the DNA assembly instructions to build that first ribosome. You run into a chicken and egg dilemma - seems like you would first need a ribosome to build the first ribosome. Not only that, seems like you would first need a living cell to build the first living cell! I may have to rethink my evolutionary assumptions on this issue. I honestly have a difficult time believing this whole transcription, translation, protein synthesis process in the first living organism came about through random natural processes - even over millions of years.

Reply @SpiritualLifeAdvisor 2 years ago Viral genes, bacterial, and fungal genes make up the complex organism called the human being. Plants are more advanced because they have incorporated MORE viral/bacterial/fungal genes into their genome sequencing than mammals. Meaning they have more ways to morph, adapt, and create defenses against its environment for survival. Plants will always survive past the mammals and always will regulate the ecosystem because they have nearly 100% of the ecosystems genes incorporated within its own genome.

Reply @julioequinones 3 years ago (edited) 1:15:51 two questions where asked, the first of which was answered as if for both. The spirit of the question layed with the second, which was not interpreted by the Lecturer. Q1 answer. 90% DNA noncoding Q2 answer ~15% viral artifacts according to the lecture @ 27:50 So the answer is no, she did not get that number correct vs the Lecturer saying yes.
