E)histone amplification and DNA acetylation.

Question

Quizplus · Accepted Answer

Eukaryotic cells can regulate transcription by adding or removing methyl or acetyl groups to DNA or histone proteins. DNA methylation involves adding a methyl group to the cytosine base of DNA, which can inhibit transcription by blocking transcription factors from binding to the regulatory regions of genes. Histone acetylation involves adding an acetyl group to lysine amino acids in histone proteins, which can loosen the interaction between histones and DNA, making the DNA more accessible to transcription factors. Therefore, the potential devices that eukaryotic cells use to regulate transcription are DNA methylation and histone acetylation (choice D).
