How are histones involved in gene expression?

In: Biology [Edit categories]

Answer:

DNA strands are wrapped around the histones. In order for DNA to be accessible, histones must be modified (acetylation). If the histones are "protected" at a particular locus from modification, the genes are silenced and cannot be expressed.
