Question

The enormous diversity of protein molecules is due mainly to the diversity of:

• A. Amino groups on the amino acids
• B. R groups on the amino acids
• C. Amino acid sequences within the protein molecule
• D. Peptide bonds

Answer 1

The correct option is C Amino acid sequences within the protein molecule

The amino acids can be arranged in different order in the polypeptide chain to form a diverse array of proteins. Proteins are building blocks of the body. The proteins are made up of amino acids. The amino acids are linked together by peptide bonds to form a protein. The amino acids consist of amine group made up of nitrogen and hydrogen and the carboxyl group at the end and a side chain of R group which is specific to a particular amino acid. The sequence of amino acids determines the protein.
So, the correct answer is option c.
