The number of electrons in the outer shell determine its reactivity or tendency to form chemical bonds with other atoms.
        
             
        
        
        
Aspects such as genetic engineering have allowed for
engineering of transgenic organisms such as bacteria to produce bioproducts
such as insulin to addresses medical disorders
such as diabetes.  Another is the innovation of whole-genome sequencing that allows researchers
to determine genetic predisposition of a particular person to particular diseases. 
 
        
                    
             
        
        
        
<span>In cup fungi, the spore-producing asci are located on the inner surface of the mature fruiting body. Spores are released in a cloud when the asci break open. Gilled mushrooms have basidia located on the gills on the underside of the cap. The spores are dropped from the gills when mature.</span>
