Question

The product of the Miller-Urey's experiment is

• A. Aspartic acid
• B. Acetic acid
• C. Hydrogen cyanide
• D. All of the above

Answer 1

Answer: (A)

Aspartic acid

In the Miller-Urey experiment, aspartic acid was synthesized. It is an $\alpha$-amino acid that is used in the biosynthesize of proteins. Thus it proves that inorganic substrates were able to react together and produce organic compounds, thus proving chemical evolution preceded biological evolution. So, the correct answer is 'Aspartic acid'.
