Abstract

The lipid-containing bacteriophage φ6 has a genome composed of three segments of double-stranded RNA. We determined the nucleotide sequence of a cDNA copy of the smallest RNA segment. The coding sequences of the four proteins on this segment were identified. These sequences were clustered. Three of the genes had overlapping initiation-termination codons. All noncoding sequences were at the ends of the molecule. The genes of the small double-stranded RNA segment comprised two translational polarity groups. We propose that the translational coupling is the result of an inability of ribosomes to bind independently to two of the four genes. Translation of these genes occurred when ribosomes were delivered to them by translation of an upstream gene.
