Besides the necessary basic organic monomers, compounds that would have prohibited the formation of polymers were also formed in high concentration during the Miller–Urey and Joan Oró experiments.
Osim potrebnih osnovnih organskih monomera, sastojci koji bi onemogućili formiranje polimera su također dobiveni u velikim koncentracijama tijekom Miller-Ureyevih i Joan Oróvih eksperimenata.
