  Modified ollgonucleotides. Effect of 4 vs 5-atom chimeric internucleoside linkages on duplex stability

  摘要：

  The question whether a four or a five atom non phosphorus based internucleoside link leads to stronger binding of the resulting chimeric oligonucleotides to complementary sequences has been examined by comparing melting temperatures of relevant duplexes.
