Introduction of a hydrophobic biphenyl-C-nucleotide pair into a 11-mer RNAduplex is associated with a net penalty in the free energy of duplex formation of 2.0 kcal mol(-1) or 10 degrees C in Tm, relative to DNA. These differential stabilities are of relevance with respect to the transcriptional and translational aspects of hydrophobic base-pairs.
