Draw a labelled schematic sketch of replication fork of DNA. Explain the role of the enzymes involved in DNA replication.
Role of enzymes :
1. DNA dependent : DNA polymerase catalyses the polymerisation of deoxynucleotides in 5' -3' direction.
2. DNA ligase : DNA ligase joins discontinuously synthesised fragments of DNA called okazaki fragments on one of the template strands.
