Histone Acetyltransferases are Directly Involved in Which of the Following

Question

Histone acetyltransferases are directly involved in which of the following?
A) Removal of histones from chromatin
B) Movement of nucleosomes
C) Chemical modification of histones
D) Termination of gene expression
E) Insertion of variant histone proteins

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.
