In 1953, Urey and Miller carried out an experiment in which they subjected a mixture of H2O, CH4, NH3, and H2 to electrical discharges. Which of the following were among the products?
A
proteins
B
amino acids
C
nucleic acids
D
ribosomes
E
all of the above
Explanation: 

Detailed explanation-1: -After letting the experiment run for a week, Miller and Urey found that various types of amino acids, sugars, lipids and other organic molecules had formed.

Detailed explanation-2: -In what became known as the Miller-Urey experiment, the two scientists combined warm water with a mixture of four gases-water vapour, methane, ammonia, and molecular hydrogen-and pulsed the “atmosphere” with electrical discharges.

Detailed explanation-3: -The mixture of gases used was methane, ammonia, water and hydrogen. The apparatus consisted of a large (5 L) and a small flask (0.5 L) connected with glass tubing so as to form a circuit.

Detailed explanation-4: -The gases used in the experiment are water, methane, ammonia, and hydrogen.
