Question

The Miller-Urey abiotic synthesis experiment and other subsequent similar experiments showed that

• A. Simple organic molecules can form spontaneously under conditions like those thought to prevail early in the earth’s history
• B. The earliest life forms introduced large amounts of oxygen to the atmosphere
• C. Life can be created in a test tube
• D. Long chains of DNA can form under abiotic conditions

Answer 1

The correct option is A Simple organic molecules can form spontaneously under conditions like those thought to prevail early in the earth’s history

In 1953, Stanley Miller and Harold Urey created conditions comparable to those of early Earth in their laboratory. They introduced water vapour, hydrogen, methane, and ammonia in a controlled glass environment called Miller-Urey apparatus. They provided energy in the form of electric discharges to resemble the lightening. The Miller-Urey apparatus produced a variety of amino acids and other organic compounds found in living organisms today.
