Explanation:
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: -DNA polymerase III holoenzyme (Pol III HE) is an enzyme that catalyzes elongation of DNA chains during bacterial chromosomal DNA replication. Bacterial cells contain several distinct DNA polymerases.
Detailed explanation-3: -DNA polymerase ɛ is used to make the leading strand, whereas DNA polymerase
