□ dna is made of nucleotides; rna is made of amino acids.
□ dna uses deoxyribose; rna uses ribose.
□ hydrogen bonds hold rna stands together, but not dna strands.

Explanation:

1. DNA contains deoxyribose sugar while RNA has ribose sugar. This is a key structural difference in their nucleotides.
2. DNA uses thymine as one of its nitrogen - bases, while RNA uses uracil instead.
3. DNA is typically double - stranded forming a double - helix structure, and RNA is usually single - stranded.

Both DNA and RNA are made of nucleotides, and hydrogen bonds hold the strands of DNA together as well as play roles in RNA secondary structures.

Answer:

• DNA uses deoxyribose; RNA uses ribose.
• DNA uses thymine; RNA uses uracil.
• DNA is double - stranded; RNA is single - stranded.
