$DNA$ fingerprinting refers to

During $DNA$ fingerprinting,the $ds$-$DNA$ splits into $ss$-$DNA$ by . . . . . . treatment.

Would it be appropriate to use $DNA$ probes such as $VNTR$ in $DNA$ fingerprinting of a bacteriophage?

$VNTRs$ are

Select the option that shows the correct sequence of the $DNA$ fingerprinting process.
$(i)$ Isolation of $DNA$
$(ii)$ Hybridization using labeled $VNTR$ probe
$(iii)$ Transfer of $DNA$ fragments to nylon membrane
$(iv)$ Separation of $DNA$ fragments by electrophoresis
$(v)$ Autoradiography
$(vi)$ Digestion of $DNA$ by restriction endonucleases

Variable number of tandem repeats $(VNTRs)$ in the $DNA$ molecule are highly useful in
