Vedclass · Answer

(D) The elements $C, H, O$ and $N$ are fundamental components of biological macromolecules.Nucleic acids ($DNA$ and $RNA$) are composed of nitrogenous bases,pentose sugars,and phosphate groups,which contain $C, H, O, N$ and $P$.Proteins are polymers of amino acids,which contain an amino group $(-NH_2)$,a carboxyl group $(-COOH)$,and a variable side chain $(R)$,thus containing $C, H, O$ and $N$.Lipids primarily consist of $C, H$ and $O$,but generally lack nitrogen (except for phospholipids or specific complex lipids).Therefore,both nucleic acids and proteins contain $C, H, O$ and $N$ in their structures.

Mineral elements $C, H, O$ and $N$ are found in the structure of which of the following?
