Miller and Urey set up an experimental "atmosphere" composed of gases thought to be present in Earth's early atmosphere.They simulated lightning with the application of electricity and looked for the monomers used to build living organisms.Subsequent experiments using additional gases that probably were present in the early Earth environment resulted in a more diverse list of organic products.Which compounds were absent from the products of Miller and Urey's experiments?
A) Nitrogenous bases found in DNA
B) Simple proteins
C) 20 amino acids
D) Six-carbon sugars
E) Uracil, a nitrogenous base
