An operon is a cluster of coordinately regulated genes. During gene expression, genetic codes from the dna code are converted into a protein. It would be wasteful to produce enzymes when no lactose is available or if a preferable energy source such as glucose were available.

?in a repressible operon, the repressor is synthesized in an active form. (b) the highest rate of tryptophan production occurs in the region around points a and e. When tryptophan is plentiful, two tryptophan molecules bind the repressor protein at the operator sequence. 11 please select the statements that are true of inducible operons to test your understanding of the differences between inducible and repressible operons (note:

Lac operon “lac operon is an operon or a group of genes with a single promoter that encode genes for the transport and metabolism of lactose in e.coli and other bacteria.” lac operon concept Coli are located next to each other in the trp operon. Attenuation assures that expression from the trp operon is off when tryptophan is present. While.

Repressible operons usually contain genes that. A repressor binds to an operator , a dna sequence within the regulatory region between the rna polymerase binding site in the promoter and first structural gene, thereby physically blocking transcription of these operons. Recall that the trp operon is a repressible operon. Although some operons are constitutively expressed, most are subject to regulation.
