Question

Quizplus · Accepted Answer

Methyl groups are known to be relatively unreactive compared to other functional groups. However, when they are added to the bases of DNA, a process known as DNA methylation, they can significantly alter gene expression without changing the DNA sequence itself. This modification typically acts to repress gene activity.
