The chirality of biopolymer has been one of the most important open questions in the origin of life. Some experiments of evolutionary molecular engineering have suggested that the function of a biopolymer does not depend on its chirality. Thus, the chirality of biopolymers might depend on the synthetic process of the biopolymer units (e.g., nucleotides, amino acids) before the RNA world.
