WebStep 1: Binding of DNA around an initiator protein complex DNA-A ATP ~30-40. The DNA B or helicase unwinds ori C (origin of replication) and extends the single stranded region for copying. Step 2: Single strand binding protein ( SSB) binds to this single stranded region to protect it from breakage and to prevent it from renaturing.

"WebAs was stated previously, DNA replication is more complex than simply unzipping the double helix and making new complementary strands. Replication in prokaryotes starts from a sequence of nucleotides on the chromosome called the origin of replication—the point at which the DNA opens up or unzips. The enzyme helicase opens up the DNA at … " - List the 4 events in dna replication
