Question

this is an image of a(n)____. amino acid nucleic acid thiol nucleotide none of the above

Explanation:

A nucleotide is composed of a nitrogen - containing base (the yellow hexagon with nitrogen atoms in the image), a pentose sugar (the blue pentagon), and a phosphate group (the circular structure with phosphorus and oxygen). An amino acid has an amino group (\(-NH_2\)), a carboxyl group (\(-COOH\)), and a side chain. A nucleic acid is a polymer of nucleotides. A thiol has a \(-SH\) group. Since the image shows the three - component structure of a nucleotide (base + sugar + phosphate), it is a nucleotide.

Answer:

nucleotide
