A technology, which has found immense use in solving cases of disputed parentage, is
Polymerase chain reaction
$DNA$ fingerprinting
Monoclonal antibody production
Recombinant $DNA$ technology
Allelic sequence variations where more than one variant (allele) at a locus in a human population with a frequency greater than $0.01$ is refered to as
$A$ : Unknown $DNA$ after hybridization with $VNTR$ probe, the autoradiogram gives many bands of differing sizes in $DNA$ profiling.
$R$ : These bands represents $DNA$ fingerprint of organism
Give differences : $VNTR$ and $ Probe$
Southern blotting is done for
$DNA$ fingerprinting using Variable Number Tandem Repeats $(VNTRs)$ is based on the observation that
