Comment on the utility of variability in number of tandem repeats during $\rm {DNA}$ finger printing.
Tandemness in repeats provides many copies of the sequence for fingerprinting, and variability in nitrogen base sequence in them. Being individual-specific, this proves to be useful in the process of $DNA$ fingerprinting.
Matching sequence of $DNA$ between two evidences, one of the criminal with the suspect is known as:
Each individual has a unique $DNA$ fingerprint as individuals differ in
