The presence of a control substance that can [reversibly, usually] bind to a Gene-On-Off location within the Dna. Turning a Gene Off can also involve the Absence of a Control Factor.
proteins that binds to a specific DNA sequence to alter the expression of a gene. The genetic switch turns genes on and off in response to specific signals.
The cream gene.
A repressor protein turns off transcription by binding to the operator region. By binding to the operator, the repressor prevents the RNA polymerase from binding to the promoter region and initiating transcription. This prevents the expression of the gene or genes downstream of the operator.
How is a gene not expressed
No. If a gene is expressed, it is turned on.
the gene is never expressed. ^^^^ this guy is a frickin idiot. and this would more of be in the cells/ biology section. What happens is a repressor binds to the operator and turns off the gene so the protein doesn't get made. and when its needed the repressor detaches and the gene is turned back on. ( this all happens on a strand of DNA )
my mp3 turns on but does not go to menu just shows the symbol of the brand then turns off
