How does the double-helical structure of DNA explain how the molecules can be copied or replicated?

A. Because of base pairing, each strand has all the information to serve as a template for the other strand.
B. Each strand receives the information from the DNA polymerase attached to the replication fork.
C. The nitrogenous bases on one strand are copied to the other strand.
D. The nitrogenous bases line up on each strand and are attached to each other.

Answer:

A. Because of base pairing, each strand has all the information to serve as a template for the other strand.

Step-by-step explanation:

Deoxyribonucleic acid (DNA) is a molecule composed of two antiparallel polynucleotide chains. This double helix serves as a template for its own duplication. DNA templating refers to the process by which a portion of the DNA molecule in a single strand is used as a template to be copied by complementarity base pairing. According to base-pairing rules, Adenine (A) always pairs with Thymine, while Guanine (G) always pairs with Cytosine (C). These nucleotide bases are each linked with their complementary base by hydrogen bonding. When base pairs separate, the hydrogen bond acceptor and donor groups of each strand allow the addition of nucleotides and synthesis of new DNA strands, a process catalyzed by specialized enzymes (DNA polymerases).
