What is the role of enzymes in the replication of DNA?

What role do enzymes play in DNA Replication? RNA uses one strand of DNA as a template to assemble nucleotides into a strand of RNA. RNA polymerase binds to DNA and separates the DNA strands. Then, uses one strand of DNA as a template from which nucleotides are assembled into a strand of RNA.

Accordingly, what enzymes are necessary for DNA replication?

Enzymes Required for DNA replication
  • Helicase. Opens up the double strand.
  • DNA polymerase. Responsible for the actual synthesis of DNA, brings nucleotides.
  • Ligase. Joins together small newly synthesized pieces of DNA called Okazaki fragments.
  • Primase. Adds an RNA primer so that DNA synthesis can begin.

Which enzymes are responsible for DNA replication?

DNA Polymerase - The enzyme responsible for catalyzing the addition of nucleotide substrates to DNA both during and after DNA replication. Primase - The enzyme responsible for initiating synthesis of RNA primers on the lagging strand during DNA replication.

What is the main enzyme that is involved in DNA replication?

The second two activities of DNA Pol I are important for replication, but DNA Polymerase III (Pol III) is the enzyme that performs the 5'-3' polymerase function. Primase - The requirement for a free 3' hydroxyl group is fulfilled by the RNA primers that are synthesized at the initiation sites by these enzymes.
