Final answer:
The structure of DNA facilitates replication through antiparallel strands and complementary base pairing. Enzymes are also involved in unwinding, separating, and building new strands.
Step-by-step explanation:
The structure of DNA facilitates replication in several ways. One of the key features is that DNA strands are antiparallel, which means they run in opposite directions. This allows for complementary base pairing, where adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G). This ensures that the new DNA strands are an exact copy of the original.
Additionally, DNA replication requires enzymes, such as DNA helicase and DNA polymerase, to unwind the DNA strands, separate them, and build the new complementary strands. These enzymes are essential for the replication process.
