Final answer:
The site where DNA replication proteins assemble and DNA replication initiates is called the origin of replication. During this process, specific nucleotide sequences called origins of replication are recognized by proteins, and an enzyme called helicase unwinds the DNA helix, forming Y-shaped structures known as replication forks.
Step-by-step explanation:
The site where DNA replication proteins assemble and DNA replication initiates is called the origin of replication.
During this process, specific nucleotide sequences called origins of replication are recognized by proteins, and an enzyme called helicase unwinds the DNA helix, forming Y-shaped structures known as replication forks.
These replication forks extend in both directions as replication proceeds.
