Although brome mosaic virus RNA3 has only one translatable cistron, it can bind two 80S ribosomes at initiation. One ribosome binds at the first AUG codon (base 92-94). The other binds nearer the 5' end at an entry or holding site. Disome formation is thus unrelated to a silent cistron approximately 1,000 bases downstream.
尽管雀麦花叶病毒RNA3只有一个可翻译的顺反子,但它在起始阶段能结合两个80S核糖体。一个核糖体在第一个AUG密码子(第92 - 94位碱基)处结合。另一个在靠近5'端的一个进入或结合位点处结合。因此,二聚核糖体的形成与下游大约1000个碱基处的一个沉默顺反子无关。
