  1. Question 1

    Q1. During protein synthesis on a ribosome, a peptide bond is formed. Between which two functional groups of adjacent amino acids does this bond occur?

    • A) Amino group and carboxyl group
    • B) Carboxyl group and R-group
    • C) Amino group and R-group
    • D) Two different amino groups

    Answer: Amino group and carboxyl group

    Explanation: Peptide bonds form between the amino group of one amino acid and the carboxyl group of another. Peptide-to-peptide bonding is structurally impossible.
