GENE REGULAAAATION IN EUKARAY OTESSS
Young thug wants to get educated
Yo, I need you to tell me about gene regulation in eukaryotes.
Sure why not.
There is a system for gene organization in eukaryotes because they have more DNA than prokaryotes.They also have two regulatory systems: histone packing and unpacking regions and transcription factors.
What are these Histones even doing in my body?
Histones are responsible for packing and unpacking DNA regions. For example, acetylation loosens DNA which allows more transcription. In contrast, methylation packs DNA tightly which results in less transcription.
Imma let you finish, but what about Transcription factors.
The transcription factors regulate the RNA polymerase access to the promoter which can turn the expression "on" or "off".
Why do we have all these regulations in my body?
cells need to find and trigger gene at the right time. Also, the cells need a way to turn genes on or off.
what happens if Cell's don't want to do all these regulations?
