Variable Number Tandem Repeats (VNTRs) are crucial in DNA fingerprinting because they:
Are highly conserved sequences found in all individuals
Code for essential proteins involved in DNA replication
Show high variability in their number of repeats between individuals
Are only found in specific tissues
