DNA REPLICATION 1) Semiconservative Replication According to this model, DNA Replication would create two molecules. Each of them would be a complex of an old (parental and a daughter strand).

2) Conservative Replication According to this model, the DNA Replication process would create a brand new DNA double helix made of two daughter strands while the parental chains would stay together. 3) Dispersive Replication According to this model the Replication Process would create two DNA double-chains, each of them with parts of both parent and daughter molecules.
