Answer:
c. binds to allolactose and becomes inactive, allowing lac gene expression to occur.
Explanation:
Interaction between allolactose and repressor leads to allosteric repulsion which makes repressor inactive leading to the lac gene expression. This is the reason why allolactose is known as the inducer of lac operon becasue it causes gene expression in lac operon.
In the absence of allolactose, the repressor binds the operator and does not allow RNA polymerase to do transcription.
Answer:
Well, first off, I live in America. In America, it is night time per se. And on the other side of the earth, it is the afternoon. Because, the earth orbits the sun. So, it changes depending on the time of day it is.
Explanation:
Frederick Griffith's discovery on the theory of genetics is credited to his experiment on mice. He subjected them to different strains of pneumonia bacteria. He concluded that there is an unidentified force that leads to the formation of different strains from what the mice were subjected to. This leads to the discovery of DNA, the carrier of traits. Scientist before did not know how the trait is passed on not until Griffith's experiment.
When the rates of the forward and reverse reactions are equal. The system is dynamic because individual molecules react continuously. It is at equilibrium because no net change occurs.
