   There are three compelling reasons that suggest that the first set of prebiotic coding sequences to be translated were repeats of base oligomers, the numbers of bases in oligomeric units not being multiples of three.

   As a result, studies of uncoded peptide bond formation are founded in using NCAs as substrates (even when obtained as the reactive species of the non-prebiotic CDI activation) for mimicking prebiotic processes.

   Evidence of the prebiotic properties of polydextrose (PDX), resistant maltodextrin (RMD), and other soluble fiber sources are slowly emerging, but the body of evidence is small compared to the gold standard of fructo oligosaccharides (FOS) and inulin.
