A novel nucleic acid model using
-peptide ribonucleic acid (
-PRNA) possessing alternative
-PRNA/lysine and
-PRNA/arginine sequences, where the lysine or arginine residue are expected to stabilize the complex not only by the conventional hydrogen-bonding interactions between the complementary nucleobase pairs but also through the electrostatic interactions between basic amino acid side-chain groups and DNA's phosphate anions on the backbone. These
-PRNAs form stable sequence-specific complex with the complementary DNA.
