A)translation.
B)enhancer expression.
C)methylation.
D)promoter expression.
E)operator suppression.

Question

Quizplus · Accepted Answer

The protein that binds to clusters of 5-methylcytosine is called a methyl-CpG binding protein, which specifically recognizes and binds to methylated cytosines. Methylation is a key epigenetic modification that can regulate gene expression by either inhibiting or promoting transcription. In this case, the binding of methyl-CpG binding protein to methylated regions in DNA ensures that the associated gene will remain in the "off" position by preventing transcription factors from binding to the DNA and initiating transcription.
