Proving that DNA Replication is Semiconservative

For Meselson and Stahl to prove that DNA replication proceeds in a semiconservative manner, they not only had to design a clear, easily interpretable experiment, but also develop the technology to do it. The beauty of this classic experiment is that each of the possible models would produce distinct ...

Point mutation
A point mutation, or single base modification, is a type of mutation that causes a single nucleotide base change, insertion, or deletion of the genetic material, DNA or RNA. The term frameshift mutation indicates the addition or deletion of a base pair. A point mutant is an individual that is affected by a point mutation.Repeat induced point mutations are recurring point mutations, discussed below.
