Q. What type of bond connects amino acids in a polypeptide chain?
✅ Correct Answer: (B)
Peptide bond
Explanation: A peptide bond (amide bond) links amino acids by joining the carboxyl group of one to the amino group of another. Ionic bonds are electrostatic attractions, hydrogen bonds stabilize secondary/tertiary structures, and glycosidic bonds connect sugars — not amino acids.
