question 149

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.
