Peptide Nucleic Acid (PNA). Implications for the origin of the genetic material and the homochirality of life
Abstract
PNA is a pseudopeptide DNA mimic in which the natural nucleobases have been retained, but the backbone consists of {ital N}-(2-aminoethyl)glycine units to which the nucleobases are attached via methylene carbonyl linkers. The finding that PNA forms Warson-Crick-like helices with complementary DNA, RNA or PNA combined with the fact PNA is held together by amide bonds has made PNA of interest as a model for a primordial genetic material. Furthermore, the PNA backbone is achiral, while preferred chirality can be induced in PNA-PNA double helices by attached chiral ligands, thereby providing a new way of {open_quote}{open_quote}chiral amplification.{close_quote}{close_quote} Finally, it has been demonstrated that PNA-template directed synthesis of RNA and PNA is feasible. {copyright} {ital 1996 American Institute of Physics.}
