After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.

The pale lactose nonfermenting bacterie (blue arrow) are Salminella typhi. Salmonella in general does not ferment lactose (colorless colonies), Salmonella typhi,unlike other salmonallae, produce little hydrogen sulfide (H2S) gas. The resulting bacterial colonies will appear colorless with colorless or very discrete black centers.

DNA mutation, a mutation is a change in a DNA sequence, mutations can result from DNA copying mistakes made during cell division.
