Question

Which enzyme is mainly responsible for DNA chain elongation during replication ? (A) DNA polymerases II (B) DNA-ligase (C) RNA polymerase (D) DNA polymerase III

Tardigrade Admin · Accepted Answer

DNA polymerase III establishes phosphodiester linkages between the adjacent deoxyribo-nucleoside phosphates in the presence of ATP/GTP, TPP and Mg2+, thereby resulting in elongation of DNA chain during replication.
