This invention relates to the field of nucleic acid chemistry, more specifically to the field of compositions and processes that can bind to nucleic acids, including compositions and processes that by doing so have use in the capture, detection and sequencing of nucleic acids, and most specifically to nucleoside analogs that incorporate nucleobase analogs that are able to bind to different natural nucleobases with nearly equal affinity, and therefore display a degree of ambiguity, or universality, in their binding pattern. Such nucleobase analogs, when incorporated into oligonucleotides, allow the oligonucleotides to bind with nearly equal affinity and/or melting temperature, to a complementary strand, template the synthesis of oligonucleotide from primers that have a distribution of sequences, and support the sequencing of oligonucleotides. Thus, these have use in human diagnostics, especially when polymorphisms are present in a population.
这项发明涉及核酸化学领域,更具体地涉及能够结合核酸的组合物和过程的领域,包括通过这样做用于捕获、检测和测序核酸的组合物和过程,尤其是涉及能够与不同天然核碱基具有几乎相等亲和力的核苷酸类似物的核碱基类似物,因此在它们的结合模式中显示一定程度的模糊或普遍性。这种核碱基类似物一旦被纳入寡核苷酸中,允许寡核苷酸与互补链几乎具有相等的亲和力和/或熔化温度结合,模板从具有序列分布的引物中合成寡核苷酸,并支持寡核苷酸的测序。因此,这些在人类诊断中有用,特别是在人群中存在多态性时。
