Chemical instability of some of the phosphodiester bonds, often observed in large RNAs, visualizes the autocatalytic properties of this class of nucleic acids. Unexpectedly, selective hydrolysis occurs also in short oligoribonucleotides (as short as a tetramer or hexamer). Herein, we describe additional experiments which support the conclusion that the hydrolysis is not due to ribonuclease contamination but is of autocatalytic origin and is related to the sequence and structure of single-stranded oligomers. Moreover, we show that the presence in the reaction mixture of polyamines, such as spermidine, is essential for hydrolysis of oligoribonucleotides.

The rational design of self-assembled nanobio-molecular hybrids of peptide nucleic acids with single-wall nanotubes rely on understanding how biomolecules recognize and mediate intermolecular interactions with the nanomaterial's surface.
