Vedclass · Answer

(B) $DNA$ fingerprinting was developed by Alec Jeffreys. $(a)$ It relies on $DNA$ polymorphism,which is the variation at the genetic level,as the basis for identification. This is correct. $(b)$ It utilizes Variable Number Tandem Repeats (VNTRs) as probes,which are highly polymorphic and useful in identification. This is correct. $(c)$ Minisatellites are indeed used to synthesize radioactive probes,but they typically range from $0.1$ to $20 \ kb$ in size,and the repeat units are usually $10-60 \ bp$. This statement is generally considered correct in the context of the technology. $(d)$ Gel electrophoresis is used to separate $DNA$ fragments based on size,not to amplify them. $DNA$ amplification is performed using Polymerase Chain Reaction $(PCR)$. Therefore,statement $(d)$ is incorrect. Since $(a)$,$(b)$,and $(c)$ are correct and $(d)$ is incorrect,the correct option is $(b)$.
