Question

Quizplus · Accepted Answer

The enzyme responsible for adding methyl groups to histone proteins is called histone methyltransferase (HMT). Option E is the only choice that correctly identifies this enzyme. Option A refers to an enzyme that adds acetyl groups to histone proteins, option B refers to an enzyme that removes acetyl groups, option C is a combination of acetyltransferase and methyltransferase, and option D refers to an enzyme that adds acetyl groups but not methyl groups.
