Final answer:
After attaching to the origin of replication and unwinding the DNA, several events occur during DNA replication, including the opening of the DNA, synthesis of new DNA strands, removal of RNA primers, and sealing of gaps.
Step-by-step explanation:
After the initiator protein attaches itself to the origin of replication and the DNA begins to unwind, several key events occur during DNA replication. First, helicase opens up the DNA, forming replication forks that extend bidirectionally. Single-strand binding proteins coat the DNA to prevent the double helix from rewinding. Topoisomerase binds ahead of the replication fork to prevent supercoiling. Primase synthesizes RNA primers, which are then elongated by DNA polymerase III to form new DNA strands. The RNA primers are eventually removed and the resulting gaps are filled by DNA polymerase I. Finally, DNA ligase seals the gaps, completing the replication process.
