由于总线上没有驱动时的电压为0V,而0V输入电压刚好处于接收器的未定义门限区域(UTR):-200mV~+200mV,因此,可能造成接收器输出状态的不可预测,从而使RS-485接收器在受到外部干扰时可能产生一个由高电平到低电平...

目的:利用已有质粒构建带GF P报告基因的启动子鉴定质粒,并用此质粒鉴定丙型肝炎病毒5非翻译区(HCV 5 ' - UTR)启动基因表达的活性。
Results it was found by sequence contrast that some mutation sites occurred mainly on UTR region, and a lot of protein sequences changed according to changes of genes coding region.
结果经序列比对发现突变位点较多发生在U TR区域,同时一些基因的编码区域也发生蛋白序列的变化。
