Choose the correct option for a molecular probe.
$I -$ Long chain of nucleic acid
$II -$ Double-stranded
$III -$ Single-stranded
$IV -$ Short chain of nucleic acid

Matching sequence of $DNA$ between two evidences,one of the criminal with the suspect is known as:

If a probe is made of radioactively labelled $dsDNA$ and is allowed to hybridise to its complementary $DNA$ in a cloned cell followed by detection using autoradiography,which of the following statements is considered wrong?

In $DNA$ fingerprinting technique, . . . . . . probe is used for hybridization of $DNA$ fragments.

$VNTRs$ are

Arrange the various steps of $DNA$ fingerprinting technique in the correct order.
$(I)$ Separation of $DNA$ fragment by electrophoresis.
$(II)$ Digestion of $DNA$ by restriction endonucleases.
$(III)$ Hybridization using labeled $VNTR$ probe.
$(IV)$ Isolation of $DNA$.
$(V)$ Detection of hybridized $DNA$ fragments by autoradiography.
$(VI)$ Transferring of separated $DNA$ fragment to synthetic membranes.
