Definition

Combinatorial libraries are mixtures of large numbers of compounds. To study the origin and evolution of biomolecules such as nucleic acids or proteins, vast combinatorial libraries have been synthesized that contain up to 1015 different random RNA molecules or up to 1013 random polypeptides. These libraries are used in conjunction with in vitro selection techniques such as SELEX (systematic evolution of ligands by exponential enrichment) or mRNA display to test the hypothesis of the emergence of functional biomolecules from random sequence space.
