Final answer:
Displacement replication is a process in which one strand of DNA displaces the original single strand from the chromosome. It is commonly observed in the replication of circular DNA molecules like plasmids.
Step-by-step explanation:
The process described in the question is called displacement replication. Displacement replication occurs when one strand of DNA displaces the original single strand from the chromosome. This process is commonly observed in the replication of circular DNA molecules like plasmids. During displacement replication, a single-stranded break is introduced into the chromosome to release it from other chromosomes, and then the DNA is resealed.
