The structure and application of oligodeoxyribonucleotides containing modified, degenerate bases
Nucleic Acids Symposium Series
|January 1, 1991
Abstract:
Oligodeoxynucleotides containing modified pyrimidine bases which can stably hydrogen-bond to adenine and guanine and also purine bases which pair with thymine and cytosine residues in duplexes have been synthesised, as have oligomers with both such analogues. Structures have been investigated by melting transitions, n.m.r. spectroscopy and crystallography and then interpreted in terms of tautomeric equilibria. Applications to hybridisation probes and primers will be discussed.
