Answer- (b) Cytosine
Explanation- The fifth base of DNA is methylated.
Methylation process occurs with the addition of the methyl group at
the 5-carbon of the cytosine

Adenine, cytosine, guanine are present in both DNA and RNA. Thymine and uracil are exclusive for DNA and RNA respectively. Explain why it is advantageous for DNA to contain thymine, not uracil. 0. Gout is a common, painful form of arthritis. It causes swollen, red, hot and stiff joints. Gout happens when uric acid builds up in your body. It is treated with allopurinol. What is the biochemical bas is of this treatment?
In RNA, uracil forms a complementary base pair with O guanine thymine adenine cytosine
