rna nucleotides

Explanation:

DNA nucleotides have deoxyribose sugar and nitrogenous bases adenine, guanine, cytosine, and thymine. RNA nucleotides have ribose sugar and nitrogenous bases adenine, guanine, cytosine, and uracil. So, we check the sugar and nitrogenous base in each diagram.

Answer:

• DNA nucleotides: The first (adenine + deoxyribose) and third (guanine + deoxyribose) diagrams.
• RNA nucleotides: The second (uracil + ribose) and fourth (cytosine + ribose) diagrams.
