1. What is the most important message delivered by this paper?
ced-1 and ced-2 affect cell death in C. elegans
ced-1 and ced-2 affect engulfment of dead cells
In programmed cell death, cells probably die by suicide rather than phagocytosis
ced-1 and ced-2 are different genes that affect dead cell engulfment
None of the above

2. nuc-1 is a gene That is important for killing the cells
That is important for degrading DNA from apoptotic cells and ingested bacteria
That is important for degrading DNA from apoptotic cells
That is important for cell corpse engulfment
None of the above

3. The fact that cells in the ced-1(-/-) mutant die at normal times suggests
cells do not die by phagocytosis
Phagocytosis is dispensable for cell killing
ced-1 does not control the timing of cell death
ced-1 does not change the cell fate
All of the above

4. The dot indicated by the arrowhead in Fig. 3 upper right is
an apoptotic cell by itself
a non-apoptotic cell
apoptotic cell debris inside an engulfing cell
an engulfing cell
None of the above

5. ced-1 and ced-2 are the same gene act in the same pathway
both promote cell killing
both promote degradation of DNA in dying cells
None of the above

6. Based on the paper, ced-1 and ced-2
are also involved in other forms of cell death
act downstream of the nuc-1 gene
act upstream of the nuc-1 gene
mediate the increase in refractility of dying cells
None of the above
