Variable number of tandem repeats $(VNTRs)$ in the $DNA$ molecule are highly useful in

Select the correct sequence for the process of $\text{VNTR}$ technique.
$X =$ Hybridisation using labelled $\text{VNTR}$ probe
$Y =$ Digestion of $\text{DNA}$ by restriction endonucleases
$Z =$ Transferring (blotting) of separated $\text{DNA}$ fragments to synthetic membrane,such as nitrocellulose

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

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?

Arrange the following steps of $DNA$ fingerprinting in a correct sequence.
$A$. Isolation of $DNA$ and its digestion by restriction endonucleases.
$B$. Hybridisation using a labelled $VNTR$ probe.
$C$. Transferring of separated $DNA$ fragments to synthetic membranes.
$D$. Detection of hybridised $DNA$ fragments by autoradiography.
$E$. Separation of $DNA$ fragments by electrophoresis.
