DNA typing is performed by demonstrating differences in length of specific DNA sequences. This can be done by digestion of DNA with restriction enzyme(s), followed by Southern blot hybridization using a probe specific for the polymorphic site. Polymerase chain reaction (PCR) techniques are becoming widely applied to the same task, and have several advantages over […]
