WebEtt operon är en väsentlig DNA -sekvens för ett mer effektivt drivande av transkription, och därmed proteinsyntes. Ett operon kan betraktas som en sträcka DNA med besläktade gener som tillsammans delar ett gemensamt slutmål, jämte dess operator, promotor samt repressor som möjliggör transkription. WebThe operon is controlled by a regulatory gene S. Normally, the enzymes are synthesized only in the absence of compound B. If gene S is mutated, the enzymes are synthesized in the presence and in the absence of compound B. Does gene S produce a repressor or an activator? Is this operon inducible or repressible?
