Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

“The first molecule of life, hydrocarbon, might havemet on some surfaces that might not only have concentrated these organic compounds together but also helped organize them into patterns much like our genes". This statement belongs to:

A	Theory of biochemical evolution
B	Community clay
C	Chilly start
D	RNA world

Explanation:

Detailed explanation-1: -Assertion: Organic compounds first evolved on Earth to support the origin of life were proteins, fatty acids, and nucleic acids.

Detailed explanation-2: -The Miller-Urey experiment In 1953 American chemists Harold C. Urey and Stanley Miller tested the Oparin-Haldane theory and successfully produced organic molecules from some of the inorganic components thought to have been present on prebiotic Earth.

Detailed explanation-3: -The Miller-Urey experiment provided the first evidence that organic molecules needed for life could be formed from inorganic components.

Detailed explanation-4: -The energy needed to drive the formation of these organic molecules was derived from the sun’s radiation, electrical discharges in the form of lightening, and heat from the cooling earth.
