Example Question #1 : Evidence Of Evolution
The Urey-Miller experiment determined which of the following results?
Possible Answers:
Organic molecules can arise from inorganic precursors
The early atmosphere was composed of ammonia and methane
DNA replicates via semiconservative replication
Cyanobacteria were responsible for the oxygenation of the atmosphere
Correct answer:
Organic molecules can arise from inorganic precursors
Explanation:
The Urey-Miller experiment was used to determine if the early atmospheric conditions were favorable for the creation of organic materials. Their experiments determined that basic organic molecules, such as urea and amino acids, were able to form in early atmospheric conditions.
The Mehselson-Stahl experiment revealed the semi-conservative nature of DNA replication.
