Question

unit 1 cumulative test (characteristics of life, biomolecules, cell structure a... 42 of 42 amino acid is to protein as
○ fat is to lipid.
○ dna is to rna.
○ sugar is to fat.
○ nucleotide is to dna.

Explanation:

Amino acids are the building blocks (monomers) of proteins (polymers). Now let's analyze each option:

• Option 1: Fat is a type of lipid, not a monomer - polymer relationship.
• Option 2: DNA and RNA are both nucleic acids, different types, not a monomer - polymer relationship.
• Option 3: Sugar (like glucose) is a monomer, but fat is a lipid, not a polymer of sugar.
• Option 4: Nucleotides are the monomers of DNA (a polymer of nucleotides), which is the same relationship as amino acid (monomer) to protein (polymer).

Answer:

D. nucleotide is to DNA (assuming the last option is D; if the options were labeled differently, adjust the label but the content is "nucleotide is to DNA")
