60.Which one of the following statements about restriction fragment length polymorphisms
(RFLPs) is CORRECT?
RFLPs are the product of cleavage by restriction enzymes.
RFLPs are variations in restriction sites that result in DNA being cleaved into
RFLPs are numerous in the human population.
RFLPs can take the place of VNTRs in forensic analyses.
All of these choices are correct.
61.Can identical twins be distinguished by DNA typing? By DNA fingerprinting?
62.Genomic regions with a variable number of tandem repeats (VNTRs) used in DNA
typing are highly polymorphic with many different possible genotypes existing in a
population. However, matching patterns of bands for any one VNTR between the DNA in
a sample and the genomic DNA of a particular individual is not sufficient to establish that
the two come from the same individual. The primary reason is that:
63.The accompanying gel diagram shows the bands obtained for a single variable number
tandem repeat (VNTR) in evidence obtained at a crime scene (W) and genomic DNA
