What are the three enzymes that play a major part in DNA replication? What do they do?

1. DNA polymerase

2. DNA primase

3. DNA helicase

Explanation:

DNA replication is the process whereby the genetic material gets duplicated i.e producing an identical copy of a sequence. This process requires the aid of certain enzymes that play specific functions. Some of the important enzymes include:

- DNA polymerase is the enzyme considered to be the most important because it directly adds nucleotides to the strand based on what it reads on the template strand.

- DNA helicase is the enzyme that separates the double stranded DNA molecule into two single strands that forms a structure called REPLICATION FORK.

- DNA primase is the enzyme that adds a short RNA sequence called PRIMERS to the lagging strand of DNA in order for DNA polymerase to start its nucleotide synthesis.
