- DNA replication
- Gyrase
- Catalyses untwisting of double helix shape
- DNA helicase
- Catalyses breaking of H bonds
- Produces replication fork
- DNA polymerase
- Catalyses addition of nucleotides in 5’ to 3’ direction
- DNA primase
- Leading strand
- Synthesised continuously
- Lagging strand
- In fragments, discontinuous
- Goes in opposite direction of movement of replication fork
- Short segment produced is the Okazaki fragment
- Addition of nucleotides
- Free floating phosphonucle-otides bonded to exposed bases in original strands by complementar-y base pairing
- Sugar-phosphate backbone
- Free floating phosphonucle-otides bonded to exposed bases in original strands by complementar-y base pairing
- Gyrase
