Abstract
The synthesis of mixed backbone oligodeoxynucleotides (18-mers) consis ting of positively charged guanidinium linkages along with negatively charged phosphodiester linkages is carried out. The use of a base labi le-protecting group for guanidinium linkage offers a synthetic strateg y similar to standard oligonucleotide synthesis. The nuclease resistan ce of the oligodeoxyribonucleotides capped with guanidinium linkages a t 5' and 3' ends are reported. The hybridization properties and sequen ce specificity of binding of these deoxynucleic guanidine/DNA chimeras with complementary DNA or RNA are described.
