Answer:

The first pair of sequence.

This is because transitions are interchangeable of two ringed purines A to G or of one ringed pyrimidine C to T they therefore involves bases of similar shapes.

Transition mutations are generated at higher frequency than transformation which is interchangeable of purines for pyrimidine bases which involves exchange of one ring and two ring structures.

Aliun [14]

Answer:

B. The ddNTPs lack a 3′ hydroxyl group.

Explanation:

Dideoxynucleotides is a family of inhibitors of the DNA polymerase, its official name is 2',3' dideoxynucleotides but they are commonly called ddNTPs. One of the main characteristics of this compound is the absence of the 3'-hydroxyl group in the deoxyribose, due to the absence of this group, it is impossible to form a phosphodiester bond between nucleotides and the DNA synthesis is stopped.
