NEET Botany Molecular Basis of Inheritance Questions Solved


Column-I                                               Column-II
I. Genome of ϕ 174 bacteriophage           (A) Ribozyme, RNAase
II. Purine                                               (B) 5386 Nucleotides
III. Catalytic RNA                                   (C) Adenine and Guanine
IV. Any chemical change in DNA              (D) Mutation
The correct match is:
(a) I - D, II - B, III - A, IV - C                 (b) I - B, II - A, III - D, IV - C
(c) I - D, II - C, III - A, IV - B                 (d) I - B, II - C, III - A, IV - D

  1. A bacteriophage known as φ 174 has 5386 nucleotides.
  2. Adenine and Guanine are purines whereas Cytosine, Thymine and Uracil are pyrimidine. These are nitrogenous bases.
  3. Ribozyme and RNAase catalyzes chemical reactions.
  4. Mutation refers to the chemical change in DNA during its replication.
