Question

Quizplus · Accepted Answer

Histone acetyltransferases (HATs) add acetyl groups to lysine residues on histone proteins, which can result in a more open chromatin structure that allows for increased transcriptional activity. Therefore, HATs are involved in the chemical modification of histones.
