Drop-off during ribosome hopping.

Abstract excerpt

Ribosomes bypass a 50 nucleotide non-coding segment of mRNA between the two open reading frames of bacteriophage T4 gene 60 in order to synthesize a topoisomerase subunit. While nearly all ribosomes appear to initiate bypassing, only 50 % resume translation in the second open reading frame. Failure to bypass is shown here to be independent of the stop codon at the end of the first open reading frame and to be...
