Inducer
Inducer is a chemical (most often a substrate or any other metabolite) which inactivates the repressor of an operon. The inducer binds with the repressor, forming a repressor-inducer complex. This complex prevents the repressor from binding with the operator gene of t..
Promoter Gene
This gene is located adjacent to the operator gene. It has two functions. 1.The promoter gene marks the site at which the RNA polymerase enzyme binds. When the operator gene is turned on, the enzyme moves over the operator gene to reach the structural genes and the transcription of mRNA ..

When the operator gene is turned on, the enzyme moves over the operator gene to reach the structural genes and the transcription of mRNA ..Gene Regulation Summary
>The repressor protein binds with the operate gene, RNA polymerase cannot be allowed and hence structural genes get switched off. The repressor protein is kept in an active state by the inducer which is usually the substrate molecule. The repressible operon has the same componen..

Better than great. That was the best 45 minutes i have spent on here. We got a lot done and i have a better understanding of the material. Thanks
THE BEST tutoring i have ever seen and experienced! I am done now, but will most definitely come back for more help when needed. Thanks again tutorvista!!! :) - Carter
this tutoring helped me with each and every problem i needed help with and helped me to understand the math - ben
My daughter use to study from personal tutor for Maths, but now when she is studying through TutorVista, she gets tutoring for Maths, Science, English.. everything at a price cheaper than the Math tutor she had.
