Introducing epigenetics

By heheals

October 12, 2020




Dr Jemma Berry, lecturer in the School of Medical Sciences at Edith Cowan University, provides an engaging and insightful overview of an emerging and exciting area of molecular biology. Dr Berry provides an easy to understand introduction to two major epigenetic modifications: histone modification and DNA methylation.

The PowerPoint presentation used by Dr Berry, with accompanying presenter notes, may be downloaded from http://spice.wa.edu.au/introducing-epigenetics

  1. Hey can someone correct me if I am wrong but her statement "DNA methylation always leads to silencing a gene" is not true. If there is gene hypermethylation in promoter regions it is associated with silenced genes whereas gene promoter hypomethylation is actually associated with activation of genes

  2. Thank you for your exciting presentation madam.
    I have question;
    you have add that during during fertilization(video at 5:20) both the sperm and the egg contains epigenetic signal from their parents. So, can we say that epigentics is heritable character? I am not clear about it?

  3. So, here is a big question I have noticed as being overlooked in all conversations on epigenetics and other cell systems- In the (fabulous) recipe book analogy, what is Dr. Jemma Berry representing? Is she a ribosome on autopilot, or a sentient sub-component of the living organism? I expect this question to be disregarded in the current environment. But, in the future, I believe it will be proven out- The sentient mind of the individual directly impacts his own body at the cellular and genetic level.
