Questions The citrate (cit) operon 1. Operons are the basic unit of gene expression in prokaryotes. Explain the role of each of these operon components in prokaryotic gene expression: structural genes, promoter, repressor, and operator 2. Fully describe the E. coli cit operon as it functions in conditions without oxygen. Include promoter, repressor and operator in your description. 3. The cit operon is under negative control. What does that mean and how is this operon negatively controlled? 4. What is...

Most of what we know about the lac operon in E. coli has come from the genetic analysis of various mutants. Below is a list of mutants for regions of the operon. A + superscript indicates no mutation and normal function of that region, - indicates a knock out and no function of that region, c indicates the mutation resulted in constitutive action of that region. The effect of the mutation is determined by expression of the lacZ gene as...
