Final answer:
The point of unwinding where the 2 single strands separate from the double-stranded DNA helix is called the origin of replication.
Step-by-step explanation:
The point of unwinding where the 2 single strands separate from the double-stranded DNA helix during DNA replication is called the origin of replication.
DNA replication is a process where a DNA molecule is copied to produce two identical copies. It occurs during cell division and is essential for the transmission of genetic information.
During DNA replication, the enzyme helicase unwinds the DNA double helix at the origin of replication, separating the two strands. This creates a replication fork, where the two single strands serve as templates for the synthesis of new DNA strands.
