I’ve wanted to write an intro to “epigenetics” for a while, because when I was trying to learn about it for the first time, I found most things fell into two camps: either mainstream press with lots of hype but not much detail or jargon-filled explanations aimed at hardcore biologists with lots of prior genetics knowledge. As someone who started my PhD with little understanding of genetics, it took me quite a while to piece together information with enough detail to properly understand all the terms but not so much detail that my brain felt like melting. I wished there had been one resource which talked me through at least the basic ideas from start to finish, without assuming a tonne of knowledge beforehand – and so that’s the aim of this series of posts! For people new to genetics, this will be a crash course in all the key things to know. I will use some of the jargon so that you can learn the words, but try not to get bogged down in it – you don’t need to remember it all and I will try to explain everything as I go. Leave me a comment if I need to explain something further! For people familiar with genetics, this will probably cover a lot of old ground and you might want to just skim it then read the extra resources at the end!
So… let’s start with the hype!
