Detailed explanation-1: -One of the key molecules in DNA replication is the enzyme DNA polymerase. DNA polymerases are responsible for synthesizing DNA: they add nucleotides one by one to the growing DNA chain, incorporating only those that are complementary to the template.

Detailed explanation-2: -The central enzyme involved is DNA polymerase, which catalyzes the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the growing DNA chain.

Detailed explanation-3: -DNA Polymerase can add nucleotides only to the free 3’ end of RNA primers. Thus it works exclusively in the 5’→ 3’ direction, which basically means that DNA replication follows the 5’–>3’ direction.

Detailed explanation-4: -One of the key players is the enzyme DNA polymerase, also known as DNA pol, which adds nucleotides one by one to the growing DNA chain that are complementary to the template strand.
