Question

what is the image showing below? polynucleotide monosaccharide amino acid nucleotide

Explanation:

The structure in the image has a carboxyl group ($\ce{-COOH}$) and an amino group (not shown here, but the general structure of amino acids has a central carbon attached to $\ce{-COOH}$, $\ce{-NH2}$, $\ce{-H}$, and an $\ce{R}$ group. Here, the given structure fits the basic part of an amino - acid structure (with the assumption of the presence of the amino group in a more complete view). Polynucleotides are long chains of nucleotides. Monosaccharides have a $\ce{C - H - OH}$ structure (carbohydrate structure). Nucleotides have a sugar, a phosphate, and a nitrogenous base.

Answer:

Amino Acid
