A student examining a labeled biochemistry diagram is asked to identify the three building blocks that combine to form the monomer of nucleic acids. The student notes the central pentose sugar with two attached groups and must name them precisely.
Which of the following correctly identifies the THREE components shown in the nucleotide diagram?
- A
Amino acid, sugar, phosphate
- B
Nucleoside, ribose, polypeptide
- Ccheck_circle
Phosphate, pentose sugar, nitrogenous base
- D
Fatty acid, glycerol, phosphate
Explanation
Every nucleotide consists of a phosphate group, a 5-carbon (pentose) sugar, and a nitrogenous base.
