Proteins differ from one another because
A) the peptide bonds linking amino acids differ from protein to protein.
B) the sequence of amino acids in the polypeptide chain differs from protein to protein.
C) each protein contains its own unique sequence of sugar molecules.
D) the number of nucleotides found in each protein varies from molecule to molecule.

Question

Quizplus · Accepted Answer

Proteins differ from one another mainly because of the sequence of amino acids in the polypeptide chain. This sequence determines the protein's unique three-dimensional structure and function. The other options listed, such as peptide bonds, sugar molecules, and nucleotides, are not primarily responsible for the differences between proteins.
