Abstract
A new model is proposed based on the suggestion that stable local secondary structures of mRNA interfere with ribosome movement on mRNA and consequently reduce the translation rate. This model accounts for a different level of translation for each cistron in the polycistronic mRNA of Escherichia coli heat-labile toxin (LT) and cholera toxin. We also conclude that the mRNA secondary structures have been conserved during the evolution of the toxin genes for its functional importance.
