Question

First proteins were formed without the assistance of nucleic acids, this was experimentally confirmed by

• A. Stanley Miller
• B. S. W. Fox
• C. A. I. Oparin
• D. J. B. S. Haldane

Answer 1

The correct option is A Stanley Miller

A. Stanley Miller was an American chemist who experimentally showed that organic molecules can be synthesised from inorganic molecules. He conducted an experiment which is known as Miller's experiment in which he created early earth like atmosphere and introduced a spark of light. He noted that proteins were formed without assistance of nucleic acids.

B. S.W. Fox was a biochemist who explored how amino acids could be synthesised from inorganic molecules.

C. A.I. Oparin proposed Modern theory of origin of life according to which life on earth originated as a result of physiochemical changes which resulted in chemical and biological evolution.

D. J.B.S. Haldane was the first to unite Mendel's laws of inheritance and Darwin's theory of evolution.

So, the correct answer is 'Stanley Miller'.
