Which enzyme is needed to start DNA replication?
|
|
DNA Polymerase
|
|
|
Topoisomerase
|
|
|
Ligase
|
|
|
Primase
|
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: -Primase (catalyze the synthesis of short RNA molecules used as primers for DNA polymerase) DNA polymerase I (for filling small DNA segments during replication and repair processes)
