A novel nucleic acid model using peptide ribonucleic acid (PRNA), which contains 5-amino-5-deoxyribonucleoside as a recognition site for nucleic acids and consists D-glutamic acid (D-PRNA) instead of L-glutamic acid (L-PRNA) as a backbone structure, has been designed and synthesized. Difference between D-PRNA and L-PRNA oligomers was elucidated on the basis of the effects of chirality of
-glutamic acid backbone upon structure elucidated by CD spectra.
