Abstract

Life is characterized by a selectivity for asymmetric molecules. A great deal of theoretical and experimental work has yet to explain why living organisms utilize only L‐amino acids in proteins and D‐sugars in RNA and DNA. Also unknown is how a form of life based on asymmetric molecules evolved from an environment containing a racemic mixture of prebiotic molecules. By what mechanism did this selectivity for asymmetric molecules take place?
