Match List I with List II: List I List II A. Nucleoside I. Phosphodiester linkage between 5' and 3' carbon atoms B. Nucleotide II. -D-ribose C. Dinucleotide linkage III. Base attached at 1' position of sugar D. RNA sugar IV. Phosphoric acid attached at 5' position of nucleoside Choose the correct answer from the options given below:

Options

  1. AA-IV, B-III, C-I, D-II
  2. BA-III, B-IV, C-II, D-I
  3. CA-IV, B-III, C-II, D-I
  4. DA-III, B-IV, C-I, D-II

Correct answer

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

Step-by-step solution

A nucleoside is formed when a nitrogenous base is attached to the 1' position of a pentose sugar. (A III) A nucleotide is formed when a nucleoside is linked to phosphoric acid at the 5' position of the sugar moiety. (B IV) Two nucleotides are joined together by a phosphodiester linkage between the 5' and 3' carbon atoms of the pentose sugar to form a dinucleotide. (C I) The pentose sugar present in RNA is -D-ribose, whereas in DNA it is -D-2-deoxyribose. (D II) Therefore, the correct matching is A-III, B-IV, C-I, D
