The Y-shaped region where parental strands are unwound during replication is called what?

Explanation:
During DNA replication, helicase unwinds the double helix at the site where replication begins, creating a Y-shaped junction as the two parental strands separate and are copied. That Y-shaped region is called the replication fork. The origin of replication is simply the starting point where this process begins, while the leading and lagging strands describe how the new DNA is synthesized relative to the fork (continuous toward the fork on the leading strand, okazaki-fragmented on the lagging strand).
