In the double helix model of DNA, the structures labeled 3 and 4 below are best identified as:

• nitrogen bases
• deoxyribose sugars
• phosphate groups
• amino acids

In the double helix model of DNA, the structure labeled "e" below is best described as a/an:

• nucleotide
• nitrogen base pair
• amino acid group
• codon
