Which of the following was a limitation of the Miller-Urey experiment in the 1950s?
A) The experiment synthesized both D- and L-isomers of amino acids, but the amino acids in living things are always L-isomers.
B) The experimenters assumed that Earth's early atmosphere contained only hydrogen gas, methane, ammonia, and water vapor; however, evidence uncovered more recently suggests that Earth's early atmosphere contained many more components.
C) DNA is not self-catalytic.
