In the context of chemical evolution, DNA's structure is interesting because it suggests a possible copying mechanism. What about DNA's structure facilitates copying?
A) It has the same number of purines and pyrimidines.
B) The nitrogenous bases are located on the inside of the double helix.
C) The strands of the double helix are complementary.
D) DNA always goes from 5 prime to 3 prime.

Question

Quizplus · Accepted Answer

The complementary base pairing of the two strands of DNA allows for accurate and efficient copying. As each strand acts as a template for the formation of a new strand, the base pairing rules ensure that the new strand is complementary to the original. This results in two identical copies of the original DNA molecule.
