Web streams use a locking model to prevent multiple consumers from interleaving reads. When you call getReader(), the stream becomes locked. While locked, nothing else can read from the stream directly, pipe it, or even cancel it — only the code that is actually holding the reader can.
By the time Sanger sequencing was commercialized, the groundwork for an entirely new sequencing chemistry was already well underway. In 1985, Swedish biochemists Pål Nyren and Arne Lundin published a paper illustrating a procedure that measured the concentration of a molecule, called pyrophosphate (PPi), using an enzymatic cascade that emits light. In early 1986, Nyren realized that the method he’d helped develop could be applied to DNA sequencing, because PPi is naturally produced as a byproduct of DNA synthesis.5，详情可参考体育直播
