I. Replication of DNA (in prokaryotes)

1) Models of DNA replication : Semi-conservative, Dispersive & Conservative

2) Modes of DNA replication: Theta & rolling circle

3) Enzymes (pol I, II and III) and accessory proteins

4) Mechanism of semi-conservative replication (Initiation, elongation & termination)

II. DNA Mutations, mutagens

III. DNA repair: Direct, Photoreactivation,O6 methyl guanine DNA methyl transferase,

Excision repair, Mismatch repair, Recombination repair, SOS-error prone repair
