Now that single-molecule detection was no longer necessary, Solexa was able to develop its signature sequencing chemistry. The process takes place on a chip called a flow cell, which contains a lawn of short DNA sequences affixed to its surface. The template DNA is broken up into small fragments, and adapter sequences, complementary to the DNA on the flow cell’s surface, are added to the ends of each fragment. DNA fragments are then passed over the flow cell, where the adapter sequences bind to spots on the DNA lawn. At this point, primers are added, and an initial round of amplification takes place: the short DNA sequences on the flow cell are extended to create sequences complementary to the bound template DNA fragments, which are then washed away. The sequences present in the fragments of template DNA are now affixed directly to the flow cell.。业内人士推荐wps下载作为进阶阅读

“乌龙标价”考验的是商家的危机公关能力，也对他们的内部管理提出警示。在出现类似事件的时候，商家自然有追回损失的请求权，“羊毛党”的行为也未必合理正当。因为行业、金额与客群的差异，“乌龙标价”引发的后续舆论反应也各不相同。而无论是选择撤销还是“慷慨大度”，商家都应自负其责，在维护自身合法权益与尊重消费者之间取得平衡。，推荐阅读纸飞机官网获取更多信息
