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

Which of the following statements forms the basis of $DNA$ fingerprinting?

Arrange the various steps of $DNA$ fingerprinting technique in the correct order.
$(I)$ Separation of $DNA$ fragment by electrophoresis.
$(II)$ Digestion of $DNA$ by restriction endonucleases.
$(III)$ Hybridization using labeled $VNTR$ probe.
$(IV)$ Isolation of $DNA$.
$(V)$ Detection of hybridized $DNA$ fragments by autoradiography.
$(VI)$ Transferring of separated $DNA$ fragment to synthetic membranes.

Who developed the $DNA$ fingerprinting method?

Select the correct sequence for the process of $\text{VNTR}$ technique.
$X =$ Hybridisation using labelled $\text{VNTR}$ probe
$Y =$ Digestion of $\text{DNA}$ by restriction endonucleases
$Z =$ Transferring (blotting) of separated $\text{DNA}$ fragments to synthetic membrane,such as nitrocellulose

Which of the following works on the principle of the method developed by Frederick Sanger?
