Vedclass · Answer

(B) $DNA$ fingerprinting involves identifying differences in specific regions of $DNA$ sequence called repetitive $DNA$. These sequences show high degree of polymorphism and are referred to as $Variable$ $Number$ $Tandem$ $Repeats$ $(VNTRs)$. In the process of $DNA$ fingerprinting,these $VNTRs$ are separated by gel electrophoresis and transferred to synthetic membranes (Southern blotting). Hybridization is then performed using a radiolabeled $VNTR$ probe to detect these specific sequences,which creates a unique pattern of bands.
