- 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.

Smiling through the whole lecture. Very clear and concise rendition of epigenetics. Thank you, Dr. Berry!
Thank you for the clear, enjoyable and comprehensive lecture!
Dr. Berry is such a wonderful communicator! She makes a complicated subject very easy to understand
Dr Jemma Berry has a great gift... thanks for sharing it with us.
A very interesting explanation. Thx very much DR Jemmma Berry.
DR. BERRY, Thank you for your clear concise rendition of epigenetics. Especially, external/environmental influences.
A fantastic lecture. I will be watching more.
remarkably clear lecture. much appreciated, thanks!
i understood literally everything! what a lecturer!
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.
Thanks a lot for this lecture. It really helped me understanding further epigenetics.
Thank you......the best explanation ever👌
clearly explained, thanks!
Just as an FYI epigenetic signals aren’t erased in embryos, certain markers appear to be heritable by numerous studies
perfect and comprehensive presentation
I've read something about epigenetic mutations being inherited. But as you said, If the epigenetic informations are wiped out from the cell at the blastocyst stage, how does it passes from parents to embryos?
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?
she is very intelligent and full of empathy ...
Empathy!?
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
They do not all get erased when for the embryo. Some epigenetic signals remain.
Ciencias That is very interesting... what controls which epigenetic signals are passed on and which are erased.
Thanks for the input. Any reference on this please?
It is true that they don't all get erased, but going into the complexities of how and why that occurs was too difficult for the audience this presentation was aimed at. This presentation was an introductory explanation of Epigenetics aimed at high school science teachers.
This is high school level? Man I wish I had done biology in school instead of applied maths.
beautiful
Hey I screenshotted the youtube video and stole one of your slides for my presentation at the University of Iowa today, but I'll be sure to give you credit.
Oh great, I’m so hungry now 😒😒
Hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm,
a super smart lady in blue-jeans & tennis-shoes presenting a most excelent epicgentic brief.
Very Impressive
Mind over matter. Is true. But is a problem for mainstream science, lol
