Answer:
Results in the remodeling of chromatin that can activate or inhibit gene expression
Explanation:
Alteration of histones by addition of methyl and acetyl groups are examples of chromatin remodeling complexes. These allows for the remodeling /alteration of the chromatin state to allow transcriptional machinery and other cellular processes to have access to the DNA. This way, they can either activate or inhibit gene expression. Methylation patterns inhibits gene expression while acetylation activates gene expression and so on.
