A Process That Creates Cell Varieties

All the cells in your body have the same DNA: Your DNA.  Yes, your skin cell, bone cell, brain cell… ALL have the same DNA because they are all YOUR cells.  How is that possible?  The answer is the process of differentiation.

Differentiation is a process in which a cell only activates specific parts of its DNA in order to become a specific type of cell.  By selectively choosing which parts of its DNA to activate, a cell can become a skin cell, a muscle cell, a nervous cell…etc.

Next Generation Science Standards:

MS-LS1-3 Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.

HS-LS1-2 Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.

Additional Information


DNA is the genetic material that carries information regarding an organism’s traits.


Also called a nervous cell, it is a special cell responsible for the sending of information throughout the body.

Muscle Cell

The cell that makes up your muscles.  A type of cell that is responsible for creating bodily movements.
