Molecular Biology #4 2020

A typical animal cell contains more than 40,000 different kinds of molecules. In the past 20 years, great progress has been made in understanding how these molecules combine and interact to form a living creature.
Prof. Emeritus Barry Bowman organizes the course and offers two lectures. Two other professors from the Molecular, Cell and Developmental Biology Department at UCSC present lectures covering topics related to their research programs.
These talks are intended for a general audience. A scientific background or knowledge of biology is not expected. Barry Bowman, the course coordinator, will begin with a basic review of genes, proteins and cells.
Lecture #1. Prof. Emeritus Barry Bowman: An introduction to the basics of molecular biology
Lecture #2. Assistant Prof Josh Arribere: How quality control protects our cells
Lecture #3. Prof. Martha Zuniga: SARS Wars: Immune defenses against SARS-CoV-2 and COVID-19 pathology
Lecture #4. Prof. Emeritus Barry Bowman: Digging deeper into DNA
Barry Bowman is Professor Emeritus of Molecular, Cell and Developmental Biology at UCSC.

You are an amazing lecturer! I'm aPh.D. student, entering ion the biomolecular world... Your class was extremely helpful to solve many of my questions and improving little by little my knowledge in the field. Thank you

This is it
Only 4 lecture
I mean our chapters take more than 4 lectures 😂
I'm in class12 right now

Thank you very much.I’m really grateful to you!!
Share more lectures please.
This lecture elaborates a lot fact to me
Thank you

50% repetitive DNA could be store DNA sequences that change a wolf like mammal into a whale for example over millions of years: epigenetic closely related to environmental pressure . Body builder musculature could arise from the 50 % pool in months though .

Dear Prof, thanks for a wonderful lecture. I have 1 question. In PCR, the DNA will extend after we introduce the primer. I just wonder, when the DNA extension process will stop? Is there any mechanism to stop the process? Thank you.

[@barrybowman3172]

The extension can proceed for more than 10,000 bases, but in the PCR procedure extension is stopped in each cycle by heating the reaction mixture. In the first couple of cycles some extra long DNA chains will be made, but all the new DNA will end with at least one of the primers. In subsequent cycles if replication starts with primer A and it replicates by binds a single strand previously made with primer B, then extension will end when it runs off the end containing primer B. After a few cycles essentially all the DNA will have ends corresponding to primer A or B, and that is the only DNA that will be replicated. The long strands from the initial cycles will be less than 1 millionth of the total DNA.
