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 ' \(\mathrm{X}\) ' in it:
Exp: B The given structure represent a ribose sugar. Since, no phosphate groups is attached, hence it is not a nucleotide.
Cholesterol and amino acid does not consist of a sugar hence, it is nucleoside.
Structure of DNA/ RNA - nitrogenous base + sugar \(\rightarrow\) nucleoside + phosphate group \(\rightarrow\) nucleotide.

Condensation product of adenine, ribose and phosphoric acid is named as :
1 adenosine
2 adenylic acid
3 adenine phosphate
4 none of these
Explanation:
Exp: B Condensation product of adenine, ribose \& phosphosric acid is adenylic acid and molecular formula of adenine is \(\mathrm{C}_{5} \mathrm{H}_{5} \mathrm{~N}_{5}\) the nitrogenous bases attaches at first \(\mathrm{C}\)-sugar.

The structures that appear as "Beads - on string" in the chromatin and the number of base pairs are
1 nucleotides, 100
2 Genes, 200
3 Kinetochore, 100
4 Nucleosome, 200
Explanation:
Exp: D The nucleosome that appear as " Beads - on string" in the chromatin and the number of base pairs are 200 . The nucleosomes actually represent the beads of beads-on-string structure visible under electron microscope.
