A similar experiment was more recently done by NASA using an icy mixture of water, methanol, ammonia and carbon monoxide. The mixture was exposed to ultraviolet radiation. The results of this experiment were that no amino acids or DNA were formed, but complex organic molecules were observed. The purpose of this experiment was to determine whether:.
