Quizplus · Accepted Answer

Methylation, acetylation, and other histone modifications are associated with chromatin remodeling, which affects gene transcription. By modifying the packaging of DNA, histone modifications can make it easier or harder for transcription factors to access specific regions of the genome, ultimately turning genes on or off. CpG island methylation can also affect gene transcription, but it is not the only type of histone modification and does not explain the full scope of their importance. Histone modifications also play a role in regulating cancer genes and transposable elements, but these are not their primary functions.
