The figure presents a diagram of adding d T M P to a growing strand of D N A. A D N A template that consists of nine nucleotides is shown. Five nucleotides have already been added to the complementary strand that is growing from left to right along the template. The left end of the growing strand is labeled 5 prime, and the right end is labeled 3 prime. The left end of the template strand is labeled 3 prime, and the right end is labeled 5 prime. An incoming d T T P has three phosphate groups. Arrows indicate that the two outermost phosphate groups split off as the d T M P with the remaining phosphate group is about to join to the 3 prime end of the growing strand.

The features of this model provide evidence for which explanation of why all growing strands are synthesized in a 5′ to 3′ direction?
A. The two strands need to be antiparallel to bond properly.
B. Thymine and adenine would not bond properly if the strand grew from 3′ to 5′.
C. The translation of mRNA occurs in the 5′ to 3′ direction; therefore, the growing DNA strand must also grow in the 5′ to 3′ direction.
D. The phosphate group, attached to the 5′ carbon of the dTMP, forms a covalent bond with the oxygen atom attached to the 3′ carbon of the growing strand.
