Would it be appropriate to use $DNA$ probes such as $VNTR$ in $DNA$ fingerprinting of a bacteriophage?

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:

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?

Which of the following is the correct sequence of $\text{DNA}$ fingerprinting?
$(i)$ Digestion of $\text{DNA}$ by restriction endonucleases
$(ii)$ Hybridisation using labelled $\text{VNTR}$ probe
$(iii)$ Separation of $\text{DNA}$ fragments by electrophoresis
$(iv)$ Detection of hybridised $\text{DNA}$ fragments by autoradiography
$(v)$ Blotting
$(vi)$ Isolation of $\text{DNA}$

In Northern blotting,$RNAs$ are separated by gel electrophoresis and the $RNA$ bands are transferred onto a membrane of:

Select the incorrect statement.
