Detailed explanation-1: -During DNA replication, each of the two strands that make up the double helix serves as a template from which new strands are copied. The new strand will be complementary to the parental or “old” strand. Each new double strand consists of one parental strand and one new daughter strand.

Detailed explanation-2: -Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules.

Detailed explanation-3: -The leading strand is the strand of new DNA which is synthesized in the same direction as the growing replication fork.

Detailed explanation-4: -Once the DNA has been replicated, two DNA molecules are formed in which one being the same as the parent and the other one being a newly synthesized strand. The cell can now further undergo division and each daughter cell gets the copy of DNA same as the parent cell.

Detailed explanation-5: -The first one is called the leading strand. This is the parent strand of DNA which runs in the 3’ to 5’ direction toward the fork, and it’s replicated continuously by DNA polymerase because DNA polymerase builds a strand that runs antiparallel to it in the 5’ to 3’ direction.
