Answer:
The double helix structure of DNA allows for the molecules to be copied or replicated through the process of semi-conservative replication.
Step-by-step explanation:
The double helix structure of DNA consists of two complementary strands of nucleotides, held together by hydrogen bonds between the base pairs. Adenine (A) always pairs with thymine (T) and guanine (G) always pairs with cytosine (C).
The semi-conservative replication, which is the process of DNA replication, takes place by unwinding the double helix and separating the two strands. Each strand acts as a template for the synthesis of a new complementary strand. As a result, two identical copies of the original DNA molecule are formed, each consisting of one original strand and one new strand. This is possible because of the complementary base pairing, where A will only pair with T and G will only pair with C, allowing the strands to be copied with high accuracy. The semi-conservative replication ensures that the genetic information is accurately passed on to the daughter cells.
