A Quick Introduction to Epigenetics – with Nessa Carey

By heheals

September 19, 2020




Epigenetic modifications change the likelihood of gene expression, and through it create phenotype changes, without altering the DNA sequence itself.

Watch the full talk: https://youtu.be/9DAcJSAM_BA
Nessa’s book “The Epigenetics Revolution” is available for purchase now – https://geni.us/dOYAo

Nessa Carey is a geneticist and author of The Epigenetics Revolution. She has a degree in Immunology, PhD in Virology, was a post-doctoral researcher in Human Genetics, and a senior lecturer at Imperial College London in Molecular Biology. She’s also spent 10 years in the biotechnology industry and now works in the pharmaceutical sector.

  1. Now that was a clear and understandable presentation. I feel like I really do have a rudimentary grasp of the word now and my eyes won't glaze over the next time it comes up😊. Thanks!👍

  2. There is something here that I don't understand. If a particular gene that breaks down alcohol is permanently switched off, what happens when alcohol is reintroduced? Would it take more to get to a drunken state? Can all be switched off, and what would be the result?

  3. So if I "understood" in short: Epigenetics primarily impacts probability of expression but will not impact if expression can happen nor what it does.
