Question

sort these nucleotide building blocks by their name or classification. view available hint(s)

Explanation:

Nucleotides are composed of a phosphate group, a sugar (ribose or deoxyribose), and a nitrogen - containing base (purine or pyrimidine). We identify the structures based on their characteristic chemical features. The phosphate group has a characteristic P - O structure. Ribose has an OH group on the 2' carbon (in the pentose sugar ring), while deoxyribose lacks an oxygen at the 2' carbon. Purines have a double - ring structure and pyrimidines have a single - ring structure.

Answer:

Phosphate: The structure with the -O - P - O groups.
Ribose: The pentose sugar with an OH group on the 2' carbon (the one with multiple OH groups and an oxygen in the ring).
Deoxyribose: There is no deoxyribose structure shown in the given molecules.
Purine: The double - ring structures with nitrogen atoms.
Pyrimidine: The single - ring structures with nitrogen atoms.
