Answer:
DNA Polymerase.
Step-by-step explanation:
DNA polymerase is an enzyme that is responsible for the production and synthesis of DNA from deoxyribonucleotides.
DNA polymerase is also involved in the replication process of DNA.
DNA polymerase exists in 3 forms: DNA Polymerase I , DNA Polymerase II, DNA Polymerase III.
DNA polymerase is responsible for catalyzing the reaction in the formation a bond between the 3' OH group of the 1st nucleotide and the 5' phosphate of the 2nd nucleotide.
