Final answer:

DNA unwinds at the origin of replication with the help of helicase and single-strand binding proteins before DNA replication begins.


Explanation:

Before DNA replication can begin, the DNA double helix unwinds between the base pairs at the origin of replication. This unwinding is facilitated by helicase, forming replication forks that extend bidirectionally. Single-strand binding proteins then coat the DNA to prevent it from rewinding.
