Question

The following enzyme is responsible for the bulk of DNA synthesis during replication: Group of answer choices DNA Polymerase I DNA Polymerase II DNA Polymerase III DNA Polymerase IV All four can make lots of DNA rapidly.

Answer 1

DNA Polymerase III

Step-by-step explanation:

Although all polymerases are involved in the DNA replication process, polymerase III is primarily responsible for the synthesis of DNA strands.

DNA polymerase III is required for the continuous synthesis of DNA strands. In addition to DNA polymerase III, the primase enzyme is also required for the synthesis of polymerization primer primers used by DNA polymerase III. DNA polymerase I is required for primer removal and space filling, in this process there is also the participation of DNA ligase to join the Okasaki fragments. DNA polymerase II is involved in error repair processes, while DNA polymerase IV and V have large active sites that allow greater base incorporation and therefore are more prone to errors.
