Vedclass · Answer

(D) $DNA$ fingerprinting is a technique used to identify nucleotide sequences in specific regions of $DNA$ that are unique to each individual.The difference of approximately $0.1\%$ or $3 	imes 10^6$ base pairs (out of $3 	imes 10^9 \ bp$) provides individuality to each human being.The human genome contains numerous small,non-coding,but inheritable base sequences that are repeated multiple times. These sequences are found near telomeres,centromeres,the $Y$ chromosome,and heterochromatic regions.Regions containing the same sequence of bases repeated several times are known as repetitive $DNA$. During density gradient centrifugation,this $DNA$ separates as a satellite from the bulk $DNA$,hence it is called satellite $DNA$,where the repetition of bases occurs in tandem.Satellite $DNAs$ exhibit polymorphism (the occurrence of mutations in a population at high frequency),which serves as the basis for both genetic mapping of the human genome and $DNA$ fingerprinting.While mutations in genes produce alleles with different expressions,mutations in non-coding repetitive $DNA$ have no immediate impact. These accumulated mutations form the basis of polymorphism.
