WebThe process of DNA replication can be summarized as follows: DNA unwinds at the origin of replication. Helicase opens up the DNA-forming replication forks; these are extended … DNA replication is the semi-conservative, biological process of two DNA strands copying themselves, resulting in two identical copies of DNA. This process is considered semi-conservative because, after replication, each copy of DNA contains a strand from the original DNA molecule and a strand from the newly-synthesized DNA molecule.
