One of the first uses of DNA renaturation (hybridization) was to determine the degree of similarity in DNA between different pairs of species; this, in turn, is a measure of how closely the species are related evolutionarily
In renaturation studies, the genetic similarity between two samples is measured by determining:
A. the number and locations of bands on an
electrophoresis gel.
B. the number of restriction sites in each of
the samples.
C. the temperature at which the two samples
renature.
D. the rate at which PCR amplifies the two
samples.
E. the nucleotide sequences of each sample.
