What features of the structure of DNA help explain replication

what features of the structure of DNA help explain replication

It is a double stranded molecule, and the 2 strands are mirror images of each other (A opposite of T, C opposite of G). The 2 strands are "loosely" held together by hydrogen bonds, that are easy to tear apart. During replication, the 2 strands are moved apart, and against each old strand a new strand is made. The end product is 2 DNA copies with one strand derived from the old one, and one strand newly synthesized.

So the 3 feature that play a role in replication are: double stranded DNA molecule, hydrogen bonds, and basepairing.
