The bases present in DNA are
Answer: A
The bases in DNA are adenine, cytosine, guanine and thymine.
DNA uses two purines, adenine and guanine, and two pyrimidines, cytosine and thymine, paired A with T and G with C in the double helix. Thymine is 5-methyluracil.
Uracil replaces thymine in RNA, not DNA, so every option that lists uracil is wrong: one also drops cytosine, one drops guanine, and one drops adenine. Only the first option lists all four DNA bases and nothing else.
