Select the appropriate option for $DNA$ fingerprinting.

What is the basis of $DNA$ fingerprinting?

$A$: In $DNA$ fingerprinting,hybridization is done with molecular probes.
$R$: Molecular probes are small $DNA$ segments synthesized in the laboratory with a known sequence that recognize complementary sequences in $DNA$.

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

What is it that forms the basis of $DNA$ fingerprinting?

The short repeating sequences of base pairs,which are used for $DNA$-profiling,are known as . . . . . . .
