drop zones
reset all
(chemical structure with drop zones for labeling, including a phosphate group structure, a sugar (pentagon) structure, and a nitrogenous base (purine) structure; also notes oh in rna and h in dna at the 2 position of the sugar)

Explanation:

1. The yellow boxed structure with a phosphorus atom bonded to oxygen atoms is the phosphate component of the nucleotide.
2. The blue pentagonal structure is the pentose sugar (deoxyribose/ribose) of the nucleotide.
3. The purple double-ring structure with amine groups is the nitrogen-containing base (adenine, a purine) of the nucleotide.

Answer:

• Top left drop zone (pointing to yellow structure): Phosphate group
• Bottom drop zone (pointing to blue pentagon): Sugar
• Top right drop zone (pointing to purple structure): Nitrogenous base
