In Semi-conservative replication model, the two strands of DNA uncoil from each other. It perform with the original strand and a new strand.

In Conservative replication model, DNA replication didn't open at all, but the parent strands remains undamaged by creating a new and separate  molecule that consists of two new strands.

In Dispersive replication model, DNA replication results in two DNA molecules that consists of both parental and daughter DNA.
