Question

label the parts of the nucleotide.

Explanation:

1. The group with the phosphorus (P) atom and oxygen atoms is the phosphate group.
2. The hexagonal - pentagonal ring structure with carbon, hydrogen, oxygen, etc., is the 5 - carbon sugar (a pentose sugar, like ribose or deoxyribose).
3. The part with the nitrogen - containing ring (with \(NH_2\), multiple N atoms) is the nitrogenous base.

For the label pointing to the phosphate - like structure (with P and O): Phosphate group.
For the label pointing to the pentose (5 - carbon) ring: 5 - carbon sugar.
For the label pointing to the nitrogen - containing ring: Nitrogenous base.

Answer:

• The label on the phosphate - related structure: phosphate group
• The label on the pentose ring: 5 - carbon sugar
• The label on the nitrogen - containing ring: nitrogenous base
