 Why has C. elegans proven to be a useful model for understanding apoptosis?

#Section 3: Genetics, Cellular and Molecular Biology

  1. C. elegans does not naturally use apoptosis, but can be induced to do so in the laboratory.

  2. C. elegans undergoes a fixed and easy-to-visualize number of apoptotic events during its normal development.

  3. C. elegans has large cells wherein apoptosis is easily observed without the aid of a microscope.

  4. As C. elegans ages, its cells die progressively until the whole organism is dead.
