Given below is the diagrammatic representation of one of the categories of small molecular weight organic compounds in the living tissues. Identify the category shown and the one blank component X in it

  • Category                       Component
    Nucleoside                         Uracil

  • Category                       Component
    Cholesterol                       Guanin
  • Category                       Component
    Amino acid                       NH2
  • Category                       Component
    Nucleotide                        Adenine

Solution

A.

Category                       Component
Nucleoside                         Uracil

Nucleoside is made up of ribose sugar and nitrogenous base only. Uracil forms nucleoside with only ribose sugar. So, the option with category nucleoside component uracil is correct.
