Quizplus · Accepted Answer

The portion of the histone that can be acetylated is the tail. The histone tail protrudes from the nucleosome and is accessible for modification by enzymes such as histone acetyltransferases (HATs) that add acetyl groups to lysine residues on the tail. Acetylation of the histone tail can affect the accessibility of DNA to transcription factors and other DNA binding proteins, thereby influencing gene expression.
