Who discovered $DNA$ fingerprinting?

What is the basis of $DNA$ fingerprinting?

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

Whose $DNA$ fingerprint could be represented in the figure?

Which process is used for amplification or multiplication of $DNA$ for fingerprinting?

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
