Question

Which of the following amino acid was not found to be synthesized in Miller's experiment and why?

1- Glycine 2- Aspartic acid 3- Glutamic acid 4- Alanine

Answer 1

Aspartic acid was not found to be synthesised in Miller's experiment because of its complex synthesis. Amino acids which are simple in structure and require simple reaction for synthesis were formed during the experiment whereas other with complex structure and complex biosynthetic pathway were not.
