Detailed explanation-1: -DNA synthesis catalyzed by DNA polymerase. (A) As indicated, DNA polymerase catalyzes the stepwise addition of a deoxyribonucleotide to the 3′-OH end of a polynucleotide chain, the primer strand, that is paired to a second template strand.

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: -Scientists have since identified a total of five different DNA polymerases in E. coli, each with a specialized role. For example, DNA polymerase III does most of the elongation work, adding nucleotides one by one to the 3’ end of the new and growing single strand.
