Answer
Enzymes for DNA replication:
-
Various enzymes are required as catalysts during DNA replication in living cells.
-
DNA-dependent DNA polymerase: It catalyses the polymerisation of deoxynucleotides on DNA template.
-
Helicase: It unwinds the DNA strand to form the replication fork.
-
DNA ligase: It joins the Okazaki fragments which are formed on the lagging strand.
