The enzyme that catalyzes the synthesis of new DNA molecules is called
|
|
DNA ligase
|
|
|
DNA polymerase
|
|
|
DNA gyrase
|
|
|
DNA helicase

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: -The main function of DNA polymerase is to synthesize DNA by the process of replication. It adds deoxyribonucleotides at the 3′-OH group of the growing DNA strand and synthesises the new strand in 5’→3’ direction. Different DNA polymerases perform specific functions.
