Options

  1. A(A)-(IV), (B)-(II), (C)-(I), (D)-(III)
  2. B(A)-(II), (B)-(I), (C)-(IV), (D)-(III)
  3. C(A)-(IV), (B)-(III), (C)-(II), (D)-(I)
  4. D(A)-(IV), (B)-(I), (C)-(II), (D)-(III)

Correct answer

D. (A)-(IV), (B)-(I), (C)-(II), (D)-(III)

Step-by-step solution

According to NCERT: (A) DNA Polymorphism is the basis of genetic mapping of the human genome as well as of DNA fingerprinting. Hence, (A) matches with (IV). (B) VNTR (Variable Number of Tandem Repeats) belongs to a class of satellite DNA referred to as minisatellite, which is used as a probe in DNA fingerprinting. Hence, (B) matches with (I). (C) SNPs (Single Nucleotide Polymorphisms) are single base DNA differences that occur at about 1.4 million locations in the human genome. Hence, (C) matches with (II). (D) Sat
