<h2>Clonal Selection to a Phosphorylation Cascade </h2>
Clonal selection describes the roles of compartments of the privileged operation in reply to specific antigens attacking the basis in immunology. A phosphorylation cascade is a series of situations wherever one catalyst phosphorylates is different. It makes a succession reactions driving the phosphorylation of thousands of proteins. This can be observed in omen transduction of hormone communications.
