Automated $DNA$ sequencers work on the principle of the method developed by

The basis of $DNA$ fingerprinting is:

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

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:

Give scientific reasons: $DNA$ polymorphism is the basis of genetic mapping of human genome.
