Question

which one of the following statements regarding chromatin remodelling using histone acetylation and methylation is correct? euchromatin is a compact form of chromatin that inhibits transcription. each histone tail can only either be acetylated or methylated. methylation of chromatin results in a transcriptionally active form of chromatin. lysine residues in histone tails can only be methylated. chromatin remodelling is an example of negative regulation of gene expression.

Answer 1

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.
