Oligomeric peptide ribonucleic acids (PRNA's), tethering 5'-amino-5'-deoxyribonucleosides as a recognition site for nucleic acids, has been designed and synthesized by solid phase method. PRNA 12-mer found to form stable duplex with complementary DNA.PRNA.DNA duplex composed of PRNA with mismatched DNA has 10-degree lower melting temperature than fullmatched PRNA.DNA duplex. These results demonstrate that binding of PRNA with DNA is sequence specific. It should be emphasized that the on-off switching of PRNA.DNA duplex formation has been realized by the borate added as an external factor.
