Question

Dna can undergo many types of modifications. one of these is methylation. which bases are methylated more often in human dna?

Answer 1

Cytosine base is methylated in DNA methylation.

• A biological process called DNA methylation involves the addition of methyl groups to the DNA molecule.
• Without altering the sequence, methylation can modify the activity of a DNA region.
• DNA methylation often suppresses gene transcription when it occurs at a gene promoter.
• DNA methylation is the process of adding a methyl group to DNA, further altering gene function and impacting gene expression.
• Cytosine and adenine, two of the four bases in DNA, are the bases that can be methylated.
• The most frequent DNA methylation in humans is the covalent attachment of a methyl group to the fifth carbon of the cytosine ring, producing the product 5-methylcytosine.
