  1. Question 1

    Q1. A researcher synthesizes a linear polypeptide consisting of 50 amino acid residues. How many peptide bonds are formed in this specific macromolecule?

    • A) 51 bonds
    • B) 50 bonds
    • C) 49 bonds
    • D) 100 bonds

    Answer: 49 bonds

    Explanation: A polypeptide chain contains (n-1) peptide bonds; 50 amino acids minus 1 equals 49. Option D fails by assuming bonds equal the number of monomers.
