The unusual thing about the beginning of mRNA in the λ repressor gene should be determined. The efficiency of translation of this gene should be determined. Concept introduction: λ repressor inactivated state binds to O R 1 and O R 2 sites and inhibits the transcription of phage gene. On the other hand, Cro protein binds to the same sites, to which λ repressor binds. In this way, the Cro protein inhibits the action of λ repressor.
