Incorporation of a novel pyren-1-ylcarbonyl-functionalized 4â²-C-piperazinomethyl-DNA monomer into oligodeoxynucleotides leads to increased thermal stability of duplexes with DNA complements but reduced thermal stability of duplexes with RNA complements. This DNA-selective hybridization is explored for recognition of double-stranded DNA by a novel dual strand invasion approach.
将新型芘-1-羰基官能化 4â²-C-哌嗪甲基-DNA 单体加入寡聚脱氧核苷酸中,可提高 DNA 互补双链的热稳定性,但降低 RNA 互补双链的热稳定性。这种 DNA 选择性杂交是通过一种新颖的双链入侵方法来识别双链 DNA 的。
