Question

Which of the following scientists are incorrectly paired with their theories or experiments?

विकल्प

• Fox created polypeptides called proteinoids by dripping organic molecules onto hot sand.

• Cech discovered RNA catalysts, called ribozymes, that remove intrans and catalyse RNA synthesis.

• Oparin and Haldane first produced organic compounds by simulating conditions of early Earth.

• Whittaker developed the five-kingdom system of classification.

Answer 1

Oparin and Haldane first produced organic compounds by simulating conditions of early Earth.

Explanation:

Oparin and Haldane proposed the theory of chemical evolution and the origin of life in a reducing atmosphere, but they did not themselves produce organic compounds experimentally. Their contribution was theoretical, suggesting that life arose gradually from inorganic molecules under Earth's early conditions. The experimental demonstration of organic compound formation from simple gases under simulated early Earth conditions was first done by Stanley Miller and Harold Urey in 1953.
