Each cell expresses, or turns on, only a fraction of its genes. The rest of the genes are repressed, or turned off.
The turned on genes are then first transcribed into messenger RNA by the process of Transcription.
Then the mRNA is Translated into protein by the process called Translation.
This is how the specific genes are expressed.

Speed and precision have been one of the main differences between an older and a more modern genetically modified food. In addition, these genetically modified organisms have yielded crop efficiencies although it also involves in various debates because of its unethical nature.
        
             
        
        
        
It reduces the demand of electricity because if people want to decrease the amount of air pollution they would stop using things that would cause pollution for example, people stopping to use gasoline powered cars and use electric cars more, therefore the demand for electricity will go low since lesser people will be using it.
