Provide definitions/explanations for the following terms: Probe and $VNTR$.
(N/A) $(1)$ $A$ probe is a labelled single-stranded $DNA$ or $RNA$ segment that can hybridize with a complementary $DNA$ or $RNA$ sequence of interest during a screening procedure.
$(2)$ The human genome contains numerous short $DNA$ sequences that are present as tandem repeats of varying lengths at several chromosomal locations. These Variable Number Tandem Repeats $(VNTRs)$ are highly polymorphic and serve as essential components in $DNA$ fingerprinting.
