Understand the Problem

The question is asking about the properties an amino acid must possess to be integrated into a polypeptide, focusing on its structural and bonding characteristics as depicted in the image.

Answer

D: The ability to form a covalent bond with both its NH2 group and its COOH group.

The final answer is D: The ability to form a covalent bond with both its NH2 group and its COOH group.

Answer for screen readers

The final answer is D: The ability to form a covalent bond with both its NH2 group and its COOH group.

More Information

Amino acids form peptide bonds via dehydration synthesis, where the NH2 group of one amino acid binds to the COOH group of another, releasing water.

Tips

A common mistake is to focus on side chain interactions rather than the basic amino acid structure necessary for peptide formation.
