Scientists have proposed several plausible hypotheses which share some common elements. While differing in details, these hypotheses are based on the framework laid out by Alexander Oparin (in 1924) and John Haldane (in 1929), that the first molecules constituting the earliest cells . . . were synthesized under natural conditions by a slow process of molecular evolution, and the…

The term monomer originates from mono- (one) and -mer (part). Monomers are small molecules that can be joined to form more complex molecules called polymers in a repeated fashion. Monomers form polymers by the formation of chemical bonds or the supramolecular binding through a process called polymerization.
