Question

The category of molecules produced by the Miller-Urey experiment was

A. Organic polymers

B. Inorganic polymers

C. Organic monomers

D. Inorganic monomers

Answer 1

Hint: Miller and Urey were experimented wherein they tried to mimic the conditions that were found on the early earth to study the origin of life on earth. They subjected compounds like methane, hydrogen, and ammonia to electric spark and studied the development of compounds.

Complete answer: 

Stanley Miller and Harold Urey conducted an experiment which demonstrated that several organic compounds could be formed spontaneously by stimulating the conditions of Earth’s early atmosphere. Scientists examining sealed vials preserved from the original experiments were able to show that there were actually well over 20 different amino acids produced in Miller’s original experiments. Amino acids are organic monomers.

Therefore, we can say that organic monomers that is option C is the correct answer.

Additional information:

According to the cell hypothesis, life comes from life, or cells come from cells. This is the process of biogenesis. This is a law that can be observed in the present. This is what biogenesis asserts. The absence of synthetic compounds in one's daily routine is never the result of a lack of exposure to them.

The main question is how cells got started. Several hypotheses have been proposed, including DNA first, RNA, proteins, and, surprisingly, space. None of these speculations were able to explain the complex determination of data needed for a self-replicating cell. There are no known regular causes that can explain the cell's origin.

Note: The classic experiment with Miller-Urey and similar research show that most amino acids - the chemical components of the proteins used in all living organisms, in the conditions intended for replicating Earth compounds – can be synthesised from organic compounds.
