Final answer:
Apoptotic bodies are formed when the cytoskeleton and nuclear envelope disassemble and DNA fragments. They are small membrane-bound vesicles that contain fragments of the cell's DNA and other cellular components.
Step-by-step explanation:
When the cytoskeleton disassembles, nuclear envelope disassembles, and the DNA fragments, the cell forms apoptotic bodies. Apoptotic bodies are small membrane-bound vesicles that contain fragments of the cell's DNA and other cellular components. They are formed during the process of programmed cell death, called apoptosis.
