Under the 'selfish operon' speculation, operons are viewed as mobile beginning entities that ar constantly disseminated via horizontal gene transfer of training, although their holding could be privileged by the reward of coregulation of functionally.
When does a repressible operon continue to be expressed?
As long as the product of the pathway, like tryptophan, continues to be required by the cell, a repressible operon will continue to be expressed. However, when the product of the biosynthetic pathway begins to accumulate in the cell, removing the need for the cell to continue to make more, the expression of the operon is repressed.
Where are the genes located in the operon?
The operon is a group of genes coding for proteins with related functions and they are arranged in units. The operon is made up of the promoter, structural genes and the operator. Transcription depends on the regulator, it may be located anywhere on the bacterial chromosome.
