Lecture Cycle 5 (Lecture 11)
DNA Structure, Replication, and Organization
Material Covered – DNA Replication and
Telomerase
DNA Replication
New strand assembled 5’ to 3’
- Template read 3’ to 5’
Hydrolysis of 2 phosphates
- Phosphodiester linkage elongates chain
Bacterial DNA Polymerase
Palm conserved between species
- Fingers and thumb di$er
Palm is the site of polymeriza&on
Sliding DNA Clamp – Keeps polymerase tethered to template
- Increases e.ciency
