1
New cards
Epigenetics
the study of heritable changes in gene function, without changes to the base sequence of DNA
2
New cards
Methylation
changes the structure of DNA preventing RNA polymerase from accessing the DNA and transcribing genes
3
New cards
Acetylation
uncoils DNA so RNA polymerase can more easily transcribe exposed genes
4
New cards
how methylation happens
methyl group tags DNA
5
New cards
how acetylation happens
acetyl group tags histone tails
6
New cards
why epigenetics are important
controls gene expression meaning genes can be turned off when not needed
