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 to 3.

Question

Quizplus · Accepted Answer

The strands of DNA's double helix are complementary, meaning that one strand dictates the other's sequence. This complementary pairing enables the DNA to serve as a template for replication. During replication, enzymes unzip the two strands of DNA, and each strand is used as a template to create a new complementary strand. The two resulting DNA molecules have the same sequence as the original molecule, due to the complementary pairing. This is facilitated by the specific base-pairing rules: adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C).
