Which is the basis of genetic mapping of human genome as well as $DNA$ fingerprinting?

Identify the given figure.

Arrange the following steps of $DNA$ fingerprinting in a correct sequence.
$A$. Isolation of $DNA$ and its digestion by restriction endonucleases.
$B$. Hybridisation using a labelled $VNTR$ probe.
$C$. Transferring of separated $DNA$ fragments to synthetic membranes.
$D$. Detection of hybridised $DNA$ fragments by autoradiography.
$E$. Separation of $DNA$ fragments by electrophoresis.
Choose the correct answer from the options given below:

$DNA$ fingerprinting method is very useful for:

In $DNA$ fingerprinting technique,the radioactive intermediates formed during hybridization are . . . . . . molecules.

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