|
|
DNA polymerase
|
|
|
ligase
|
|
|
primase
|
Explanation:
Detailed explanation-1: -Primase is the enzyme that synthesizes RNA primers, oligonucleotides that are complementarily bound to a nucleic acid polymer. Primase is required because DNA polymerases cannot initiate polymer synthesis on single-stranded DNA templates; they can only elongate from the 3′-hydroxyl of a primer.
Detailed explanation-2: -Primase synthesizes RNA primers complementary to the DNA strand.
Detailed explanation-3: -The enzyme is called DNA polymerase.
