During $DNA$ fingerprinting,the $ds$-$DNA$ splits into $ss$-$DNA$ by . . . . . . treatment.

In the recent past,human chromosomes have been studied by a technique using specific,often fluorescent dyes,known as

In Northern blotting,$RNAs$ are separated by gel electrophoresis and the $RNA$ bands are transferred onto a membrane of:

Dr. Lalji Singh obtained a radioactive $DNA$ probe from the $Y$ chromosome of:

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.
