The region of the brainstem that plays a role in arousing you to a state of alertness would be the reticular formation. It is responsible in regulating the sleep cycles and in detecting sensory conditions. It consists of more than 100 neural network that are for various functions.
The interphase prepares the cell to divide by enlarging the cell so that when it does divide, there will be space for the nucleus (if it applies to the cell) and the organelles. It will allow the cell to be able to function and later divide on its own. It replicates DNA so that the two future daughter cells will have an even number of chromosomes to remain the cell type that it's parent was.
