Question

1. a molecule is composed of chains of amino acids. the sequence of the amino acids determines the shape and the function of the molecule. identify the molecule.

options: deoxyribonucleic acid, protein, lipid, carbohydrate, clear all

Explanation:

To solve this, we analyze the structure of each molecule:

• Deoxyribonucleic acid (DNA) is made of nucleotides, not amino acids.
• Carbohydrates are made of sugar units (monosaccharides, etc.).
• Lipids are mostly made of fatty acids and glycerol.
• Proteins are polymers composed of chains of amino acids, and the sequence of amino acids determines their shape and function.

Answer:

protein (the option corresponding to "protein" among the radio buttons)
