Answer:
This is how cells gene regulation occur.
Explanation:
Regulation of gene expression is  very very important thing to maintain the normal levels of all body proteins according to our body"s requirement.
             During positive gene regulation enzymes of various metabolic pathways of the target cell is being activated,thus supplying the cellular need of various metabolites and proteins.
              During negative regulation various enzymes are  turned off thus blocking the formation of metabolites or proteins not required by the cell.
 
        
             
        
        
        
I cannot found the images of the microscopy anywhere. But I can explain how you can differentiate a procaryote from a eucaryote under a microscope.
The first difference between them is the size of the cell. eucaryotes are generally much bigger than procaryotes. Procaryotes are visible only at x100 objective, but eucaryotes are visible starting from the x10 zoom.
The second difference is the presence of a nucleus in eukaryotes and the absence of it in procaryotes.
The third difference is the presence of organelles in eukaryotes and the presence of a cell wall in procaryotes (only visible at electronic microscopy).
