DnaA is an initiator protein and it binds to the OriC complex at DNA boxies, one of the
important things is that it NEEDS ATP to bind.
DnaB is the helicase, it needs to unzip your jeans, I mean genes!
DnaC delivers the DnaB to the replication complex so i
Chapter 7 notes:
Bacteria are haploid, meaning they have only one copy of their genome. ( no dominant or
They also grow very fast.

Plasmids are autonomously replicating DNA molecules that exist in cells. They encode genes
that are not particularly essential to the growth or survival of the host per se. But sometimes they
provide antibiotic resistance that can benefit the host.
Proofreading and editing vs. methyl directed mismatch repair:
1) DnaQ ( subunit) can only remove mismatched nucleotides at the 3 end. Polymerase
must pause and 3 exonuclease will remove it.
2) MutS/L recognizes the mismatch and recruits MutH
3) MutH is an

Small DNA viruses: Polyomaviruses and Papillomaviruses
DNA genomes: both are circular ds DNA both undergo Genome Transcription, Genome
Replication, and Translation. Both are small. And they are needed for S-phase induction.
