A lac repressor turns off the lac genes by binding to the operator
A lac repressor turns off the lac genes by binding to the operator.
Is to code the way proteins turns genes on or off
When the lac repressor binds to the O region, RNA polymerase is prevented from beginning the process of transcription. In effect, the binding of the repressor protein turns the operon "off" by preventing the transcription of its genes. (Prentice Hall Biology Book .....Chapter 12 page 310)
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.
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.
No, an organisms' genes cannot 'turn off' at any point. They are not mechanical in any way.
The genes are controlled by the control elements in their upstream sequence. It can also regulated at RNA level by si, sh RNAs. The regulation is basically influenced by the surrounding environments. Proteins mediated the regulation of gene expression.
show the genes put togetheir to show off spring genes
my mp3 turns on but does not go to menu just shows the symbol of the brand then turns off
charge it!
It turns off if its not closed. when you put it on your hair AND CLOSES IT...it turns on.
