Definitions:

Totipotency

The ability of a cell to differentiate into any type of cell in an organism, including the extraembryonic or placental cells.

Genes

Genes are units of heredity made up of DNA, responsible for guiding the process of creating proteins that in turn, dictate cell function.

Differentiation

Development toward a more mature state; a process changing a young, relatively unspecialized cell to a more specialized cell. Also called cell differentiation.

Gene Activity

The process by which a gene's information is used to synthesize functional gene products, like proteins, influencing the cell's functions.
