What turns a bee into a Queen? The epigenetics of bee development

Описание: Worker bees and the queen bee are virtually genetically identical, however there are massive difference between these two types of bee. So what is the reason for this.
The answer to this question is something called epigenetics. This is the way that organisms decide which genes to use and which to not use.
In this video I’m going to introduce the concepts involved in epigenetics and how it works. I’m then going to explain how this all relates to the bees that I mentioned at the beginning of the video.
In order to explain this, we need to understand the role of DNA. I’ve already made a whole video on this subject, but in this video I’ll just give a quite quick overview.
The DNA in our cells is a set of instructions, it tells the cell how to make proteins and proteins do pretty much everything in our cells and bodies for that matter. A section of DNA that codes for a single protein is called a gene.
Epigenetics relates to how cells switch on and off specific genes. Switching genes off happens by a process called DNA methylation. Genes are switched on by a process called histone acetylation. Switching on and off genes makes sure that cells only have the genes that they will use switched on through their life.
I've had a go at putting chapters in the description below.
