Initiation
-
- DNA is unwound by helicase, forming an origin of replication
- Primase creates an RNA primer for DNA Pol to add onto the 3' end
Elongation
-
1.DNA Pol joins nucleotides by forming phosphodiester bonds
- Leading strand and lagging strand formed because DNA Pol can only add to 3' end
- Ligase joins Okazaki fragments
