|
Helicase
|
|
|
DNA polymerase I
|
|
|
DNA polymerase III

Explanation:
Detailed explanation-1: -One of the key molecules in DNA replication is the enzyme DNA polymerase. DNA polymerases are responsible for synthesizing DNA: they add nucleotides one by one to the growing DNA chain, incorporating only those that are complementary to the template.
Detailed explanation-2: -The DNA polymerase III holoenzyme is a complex, multisubunit enzyme that is responsible for the synthesis of most of the Escherichia coli chromosome.
Detailed explanation-3: -During elongation, an enzyme called DNA polymerase adds DNA nucleotides to the 3′ end of the template.
