During initiation of replication

#Unit 3. Fundamental Processes
  1. DNA polymerases denature A-T rich sequences at the origin.

  2. replication begins when DnaA protein binds the origin and synthesizes primers.

  3. DnaB protein cleaves the double-helix to produce template strands.

  4. two replication forks need to be created to establish bidirectional replication.
