Experiments like those first performed by Miller and Urey demonstrated that ____.

A) DNA forms readily and reproduces itself
B) amino acids and other organic compounds could form in conditions that mimicked the earth's early atmosphere
C) complete, functioning prokaryotic cells are formed after approximately three months
D) a lipid-protein film will eventually be formed by thermal convection
E) meteorites contained organic compounds

Miller and Urey's experiments showed that amino acids and other organic compounds, such as those found in living organisms, could form in a simulated early Earth atmosphere. This provided evidence for the idea that the building blocks of life could have arisen from non-living materials under the right conditions. However, the experiment did not demonstrate the formation of complete, functioning cells or DNA. The formation of a lipid-protein film was not part of this experiment, and the presence of organic compounds in meteorites was also not demonstrated by this study.
