Answer:

<h2>Histone acetylation increase transcription. </h2><h2>Whereas DNA methylation decrease transcription </h2>

Explanation:

Histone acetylation is a transcription-activating modification which occurs by the addition of acetyl group from acetyl coenzyme A, to one or more lysine residues at the ε-amino group by the enzyme histone acetyltransferases. Histone acetylation increase transcription.

DNA methylation is one of the mechanisms that cells use to control gene expression and DNA become unavailable for transcription . In DNA methylation, DNA become inactive( unavailable for transcription) so that transcription wouldn't occur.
