  1. Question 1

    Q1. When a ribosome catalyzes the formation of a dipeptide, which specific functional groups of the amino acids react with each other?

    • A) The R-group of both amino acids
    • B) The amino group and carboxyl group
    • C) Two carboxyl groups
    • D) Two amino groups

    Answer: The amino group and carboxyl group

    Explanation: Peptide bonds are formed between the amino group of one amino acid and the carboxyl group of another. The R-groups never participate in this bond.
