Abstract
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 (bases 92–94). The other binds nearer the 5′ end at an entry or holding site. Disome formation is thus unrelated to a silent cistron ∼1,000 bases downstream.
