BIO301: Cell Biology

Unit 12: Apoptosis   Apoptosis, or programmed cell death, is an orderly series of events that lead to the death of a cell in multicellular organisms. This is a normal process that balances with cell division and is controlled by a variety of internal and external signals. Apoptosis is important during developmental processes in that it eliminates unwanted cells from a variety of tissues.

Unit 12 Time Advisory
Completing this unit will take you approximately 6 hours.
