E) histone amplification and DNA acetylation.

Question

Quizplus · Accepted Answer

Eukaryotic cells use DNA methylation and histone modification to regulate transcription. DNA methylation involves the addition of a methyl group to cytosine residues in the DNA, which can inhibit the binding of transcription factors and prevent gene expression. Histone modification involves the addition or removal of chemical groups (such as acetyl or methyl groups) to the histone proteins around which DNA is coiled. This can affect the accessibility of the DNA to transcription factors and also affect gene expression.
