DNA profiling
of DNA profiling in common use. They are called restriction fragment length polymorphism (RFLP) and allele specific testing. They are similar in many ways, but they also have some differences.RFLP is ... the nylon to obtain the autoradiograph photo, containing the familiar "bar code" pattern of the DNA.Allele-specific testing can be done with a much smaller DNA sample, and takes less time than RFLP. T ...
