An iterative and regenerative method for sequencing DNA is described. This method sequences DNA in discrete intervals starting at one end of a double stranded DNA segment. This method overcomes problems inherent in other sequencing methods, including the need for gel resolution of DNA fragments and the generation of artifacts caused by single-stranded DNA secondary structures. A particular advantage of this invention is that it can create offset collections of DNA segments and sequence the segments in parallel to provide continuous sequence information over long intervals. This method is also suitable for automation and multiplex automation to sequence large sets of segments.
本文描述了一种用于 DNA 测序的迭代和再生方法。这种方法从双链 DNA 片段的一端开始,以离散的间隔对 DNA 进行测序。这种方法克服了其他测序方法固有的问题,包括需要对 DNA 片段进行凝胶分辨,以及由单链 DNA 二级结构引起的假象。本发明的一个特别优势是,它可以创建偏移的 DNA 片段集合,并对这些片段进行平行测序,从而在较长的时间间隔内提供连续的序列信息。这种方法也适用于自动化和多重自动化,对大量片段进行测序。
