Microsatellites consist of simple sequences of repeated:

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

Explain the significance of $DNA$ fingerprinting in the field of forensics.

Nowadays,it is possible to detect the mutated gene causing cancer by allowing a radioactive probe to hybridize with its complementary $DNA$ in a clone of cells,followed by its detection using autoradiography because:

The sensitivity of $DNA$ fingerprinting can be increased by using ..........

Who discovered $DNA$ fingerprinting?
