(4) Since this sequence contains only one half of each possible Watson-Crick base pair, one might expect that it would behave "properly" and exist as a nice unstructured line of chemical "letters." On the contrary, it folds into a very complex structure having nothing to do with Watson-Crick base pairing (figure 1c).
High-resolution melting analysis relies on a central principle of molecular diagnostics: the Watson-Crick base pairing of double-stranded DNA, for which the melting temperature ([T.sub.m]) depends on the number, type, and succession of the component base pairs.
Some regions of an rRNA molecule hydrogen bond by Watson-Crick base pairing; in these "stems," nucleotide sites that pair tend to covary through evolutionary time (Wheeler and Honeycutt 1988).
This compensatory change restores Watson-Crick base pairing and presumably the functional structure of the rRNA.
