Acetylation reduces the interaction between the histones and the DNA strand; this relaxed conformation permits increased interaction with transcriptional machinery.

Acetylation increases the interaction between the histones and the DNA strand; this conformation permits increased activation of polymerases.

Acetylation activates transcription factors near the histone; this permits increased transcriptional activity at a given locus.

Acetylation removes methyl groups from the DNA sequence, thus relieving the repression that they induce on transcription.

Acetylation increases phosphorylation at crucial enhancer sites on the DNA sequence, thereby increasing transcription at those loci.
