Detailed explanation-1: -DNA replication is semi-conservative because in the replication process the resulting DNA helix is composed of both a new strand and an old strand. This occurs because of the complementary base pairing, I.e. each nitrogenous base only pairs with its complementary pair.
Detailed explanation-2: -Answer and Explanation: The right option is c) Both of the original DNA strands act as templates during replication.
Detailed explanation-3: -The replication of DNA is semi-conservative and depends on complementary base pairing. Helicase unwinds the double helix and separates the two strands by breaking hydrogen bonds. DNA polymerase links nucleotides together to form a new strand, using the pre-existing strand as a template.
