The addition of the propynyl group at the 5 position of pyrimidine nucleotides is highly stabilising. We have determined the thermodynamic stability of the DNA.RNA hybrid r(GAAGAGAAGC)*d(GC(p)U(p)U(p)C(p)U(p) C(p)U(p)U(p)C) where p is the propynyl group at the 5 position and compared it with that of the unmodified duplex and the effects of methyl substitutions ...
