Remarkably stable, G[BOND]C pairing in alanyl peptide nucleic acids (PNAs) occurs in three possible pairing modes depending on the conditions. G/C alternating alanyl PNA oligomers can form linear, bandlike, higher order structure when the sequence overlap (see schematic representation on the right).
