CARB 59 |
| In order to examine base-base stacking interactions within nucleic acids, 15-mer oligodeoxynucleotides were prepared bearing a single 4-substituted phenyl or 5-substituted indole residue. Upon hybridization with complementary DNA, the stabilities of the resulting duplexes were probed with UV thermal denaturation experiments. Substituent effects on the hybridization free energies will be presented. Correlations between the structures of the modified residues and their stacking with flanking base pairs elucidate important relationships which are conserved regardless of size or substitutent orientation. |
