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
(a)
(b)
(c)
(d)
Solution
A nucleoside consists of a nitrogenous base covalently attached to a sugar (ribose or deoxyribose), whereas a nucleotide consists of a nitrogenous base, a sugar (ribose or deoxyribose) and one to three phosphate groups.
In the given diagram, if X is uracil, a nitrogenous base, a nucleoside is obtained and hence is the correct option.
