A. ced-1 and ced-2 affect cell death in C. elegans
B. ced-1 and ced-2 affect engulfment of dead cells
C. In programmed cell death, cells probably die by
suicide rather than phagocytosis
D. ced-1 and ced-2 are different genes affect dead
cell engulfment
E. None of the above
nuc-1 is a gene
A. That is important for killing the cells
B. That is important for degrading DNA from
apoptotic cells and ingested bacteria
C. That is important for degrading DNA from
apoptotic cells
D. That is important for cell corpse engulfment
E. None of the above
That fact that cells in the ced-1(-/-)
mutant die at normal times suggests
A. cells do not die by phagocytosis
B. Phagocytosis is dispensable for cell
killing
C. ced-1 does not control the timing of
cell death
D. All of the above
