Allelic sequence variations where more than one variant (allele) at a locus in a human population with a frequency greater than $0.01$ is referred to 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 Northern blotting,$RNAs$ are separated by gel electrophoresis and the $RNA$ bands are transferred onto a membrane of:

Repetitive sequences are stretches of $DNA$ with repeated bases many times in a genome, but
$(a)$ These sequences are of no transcriptional function
$(b)$ These are associated with euchromatin region
$(c)$ These help to identify a person on the basis of their $DNA$ specificity

Give differences: $VNTR$ and $Probe$.

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