ANS: B
The consistent pairing of adenine with thymine and of guanine with cytosine is known as com-plementary base pairing; thus, A complements to T and C to G and vice versa throughout the strand. A complements to T; thus, the first letter must be a T. U does not represent a complement in the sequence.
