  1. Question 1

    Q1. A ribosome links two amino acids together during translation. Which mechanism is responsible for the formation of the covalent bond between them?

    • A) Ionic bonding between R-groups
    • B) Hydrogen bonding between carbonyl groups
    • C) Dehydration synthesis between COOH and NH2
    • D) Hydrolytic cleavage of peptide chains

    Answer: Dehydration synthesis between COOH and NH2

    Explanation: Peptide bonds form between the carboxylic group of one amino acid and the amino group of another, releasing one water molecule.
