Question

Quizplus · Accepted Answer

Histones are proteins that bind to DNA, helping to package it into a compact, dense shape, which can affect the accessibility of DNA to transcription machinery and thus regulate gene expression. They do not directly prevent DNA from being translated, nor are they enzymes involved in marking cells for histology, ubiquitylation, or methylation of DNA.
