Vedclass · Answer

(A) nucleoside consists of a nitrogenous base attached to a pentose sugar. $A$ ribonucleoside specifically contains a ribose sugar,which has a hydroxyl $(-OH)$ group at both the $2'$ and $3'$ positions of the pentose ring.$1$. Structure $A$ shows a nitrogenous base (adenine) attached to a ribose sugar (with $-OH$ groups at both $2'$ and $3'$ positions),which is a ribonucleoside (adenosine).$2$. Structure $B$ shows a nitrogenous base attached to a deoxyribose sugar (lacking an $-OH$ group at the $2'$ position),which is a deoxyribonucleoside.$3$. Structure $C$ shows a nucleotide (base + sugar + phosphate group).$4$. Structure $D$ is a general representation of a nucleoside,but structure $A$ specifically depicts a ribonucleoside with the correct sugar configuration.

Column-$I$ (Biomolecule)	Column-$II$ (Characteristics)
$(A)$ $ATP$	$(p)$ One or more sugar monomers
$(B)$ $DNA$	$(q)$ The main source of energy
$(C)$ Protein	$(r)$ Two strands of nucleotides
$(D)$ Carbohydrate	$(s)$ Long sequence of amino acids
