Question

Which of the following amino acids were found to be synthesized in Miller's experiment?

• A. Alanine
• B. Glycine
• C. Aspartic acid
• D. All of the above

Answer 1

The correct option is D All of the above

• The Miller-Urey experiment explores ideas about the origin of life.
• The experiment was a success in that amino acid, the building blocks of life, were produced during the simulation.
• Miller identified just five amino acids: aspartic acid, glycine, alpha-amino-butyric acid, and two versions of alanine. Aspartic acid, glycine and alanine are common constituents of natural proteins.
• Hence, the Alanine, Glycine and Aspartic acid are amino acids formed in Miller's experiment.
• So, the correct answer is ' Alanine, Glycine and Aspartic acid are amino acids formed in Miller's experiment'.
