DNA, related to RNA yet chemically stabler, probably appeared rather late in the evolutionary history of cells. Cellular differentiation is the process by which a less specialized cell becomes a more specialized cell type. The Solar System was full of rocky debris. Differentiation occurs several times during the development of a See full answer below. When is genetic drift least likely to occur? Intrusive rocks crystallized from magmas that did not reach the surface but moved upward into cracks and voids deep in the crust. What happens to cells during differentiation? Moreover, differentiation occurs within the first semester of embryonic development. How does differentiation occur? These are the special functions of nerve cells, hepatic cells, and melanophores.

Examples of differentiated cell types in the human body include neurons, the cells lining the intestine, and the macrophages that gobble up bacterial invaders in the immune system. The process of cell differentiation allows multi-cellular organisms to create uniquely functional cell types and body plans. Over a period of time, the genetic information in RNA sequences was transferred to DNA sequences, and the ability of RNA molecules to replicate directly was lost. Cell Differentiation Definition. Sometimes such a replacement might not seriously affect the functional properties of the protein concerned, but occasionally the change may be very considerable.
