One of the First Uses of DNA Renaturation (Hybridization) Was

Multiple Choice

One of the first uses of DNA renaturation (hybridization) was to determine the degree of similarity in DNA between different pairs of species; this technique provides a measure of how closely the species are related evolutionarily. In renaturation studies, the genetic similarity between two samples is measured by determining the:

A) number and locations of bands on an electrophoresis gel.
B) number of restriction sites in each of the samples.
C) temperature at which the two samples form duplexes.
D) rate at which PCR amplifies the two samples.
E) nucleotide sequences of each sample.
