Quizplus · Accepted Answer

Bromodomain is a domain found in many transcriptional regulators and is responsible for binding to acetylated lysine residues on histones.

Answer: H
 Histone acetylase is an enzyme that acetylates lysine residues on histones, leading to a relaxation of the chromatin structure and increased transcriptional activity.

Answer: K
 Histone deacetylase is an enzyme that removes acetyl groups from lysine residues on histones, leading to a more compact chromatin structure and decreased transcriptional activity.
