Give the evidence that leads you to hypothesize as such. To indicate the order, you can simply indicate the letter for the appropriate event. Place the events in their proper order (from first to last). New order of events Events A. DNA fragmentation B. Increase in Caspase 3 activity C. Chromatic Condensation D. PARP cleavage E. Cytochrome C release 1. _____ 2. _____ 3. _____ 4. _____ 5. _____

Explanation / Answer

Answer:

1. E

(Upon induction, cytochrome c is released from the mitochondria)

2. B

(Cytochrome c induces the activation of caspases, including caspase 3 downstream of the cascade)

3. D

(Caspase 3 activates PARP)

4. C
