Question

Quizplus · Accepted Answer

Nucleosomes disassemble and reassemble by acetylation and deacetylation. The acetylation of histone tails loosens the interaction between the histones and DNA, resulting in a more relaxed chromatin structure. Conversely, the removal of the acetyl groups by histone deacetylases (HDACs) results in the tight packing of nucleosomes, leading to the formation of condensed chromatin.
