Final answer:

Methylation of chromatin results in a transcriptionally active form of chromatin.

Step-by-step explanation:

The correct statement regarding chromatin remodeling using histone acetylation and methylation is that methylation of chromatin results in a transcriptionally active form of chromatin. Methylation of lysines or arginines of H3 and H4 can open DNA for transcription, while demethylation has the opposite effect. Additionally, histone acetylation can also result in the opening of chromatin for transcription.
