The sensitivity of $DNA$ fingerprinting can be increased by the use of:

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

Arrange the following steps of $DNA$ fingerprinting in the correct sequence by selecting the appropriate option.
a) Digestion of $DNA$ by restriction endonucleases
b) Autoradiography
c) Blotting of $DNA$ fragments to nitrocellulose membrane
d) Isolation of $DNA$
e) Separation of $DNA$ fragments by electrophoresis
