Question

Quizplus · Accepted Answer

Histone acetyltransferases (HATs) acetylate the e-amino group of lysine in the histidine tails. This modification is involved in the initial events of transcriptional activation, by loosening the chromatin structure and promoting access of transcription factors to the DNA. Choice A (histone deacetylases) removes acetyl groups and restores chromatin to a repressed state. Choice C (histone activases) and D (histone kinase) are not actual enzymes involved in histone acetylation.
