Detailed explanation-1: -So, the correct answer is ‘ Alanine, Glycine and Aspartic acid are amino acids formed in Miller’s experiment’.

Detailed explanation-2: -Using paper chromatography, Miller identified five amino acids present in the solution: glycine, -alanine and -alanine were positively identified, while aspartic acid and -aminobutyric acid (AABA) were less certain, due to the spots being faint.

Detailed explanation-3: -Miller, along with his colleague Harold Urey, used a sparking device to mimic a lightning storm on early Earth. Their experiment produced a brown broth rich in amino acids, the building blocks of proteins.

Detailed explanation-4: -The two biologists made use of methane, water, hydrogen, and ammonia which they considered were found in the early earth’s atmosphere. The chemicals were sealed inside sterile glass tubes and flasks connected together in a loop and circulated inside the apparatus.

Detailed explanation-5: -In his May 15, 1953, article in Science, “A Production of Amino Acids Under Possible Primitive Earth Conditions, ” Miller identified just five amino acids: aspartic acid, glycine, alpha-amino-butyric acid, and two versions of alanine.
