LIFE SCIENCE

Detailed explanation-1: -The central enzyme involved is DNA polymerase, which catalyzes the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the growing DNA chain.

Detailed explanation-2: -Definition: The synthesis of DNA from a template strand in the 5’ to 3’ direction; leading strand elongation is continuous as it proceeds in the same direction as the replication fork.

Detailed explanation-3: -Leading Strand and Lagging Strand 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.
