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) DNA always goes from 5 to 3.
D) The strands of the double helix are complementary.

Question

Quizplus · Accepted Answer

The structure of DNA facilitates copying through the complementary base pairing of the two strands of the double helix. Each strand serves as a template for the formation of a new strand, with the sequence of nucleotides on one strand determining the sequence of nucleotides on the other strand. This complementary base pairing allows for accurate copying of genetic information during DNA replication. Choices A and B are not directly related to the copying mechanism, and choice C describes the directionality of DNA, but not how this facilitates copying.
