When first studying the replication of DNA, it was unsure in way the DNA was actually replicated. The three models that were studied by scientitsts were the conservative, semiconservative, and dispersive model for DNA replication. The conservative model shows that two newly synthesized molecules of DNA come together while the original helix is joined back together. The semiconservative model shows that each parental strand is a template strand for the newly synthesized DNA molecule and one new strand is joined to one parental strand. The dispersive model shows that parental strands are dispersed into two new double helices. After experiements done by scientists, we know today that the DNA replication is semiconservative.
