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

Some of the steps of $DNA$ fingerprinting are given below. Identify the correct sequence from the options given.
$A$. Electrophoresis of $DNA$ fragments
$B$. Hybridisation with $DNA$ probe
$C$. Digestion of $DNA$ by $RENS$
$D$. Autoradiography
$E$. Blotting of $DNA$ fragments to nitrocellulose membrane

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 which step of $DNA$ profiling,nitrocellulose membrane is used?

$DNA$ fingerprinting was discovered by .....

What is the basis of $DNA$ fingerprinting?
