Final answer:
The two main destinies of dying cells are apoptosis and necrosis (option c). Apoptosis destroys cell components, while necrosis is caused by external injury (option b). DNA profiling is possible from dead cells because the DNA is preserved in the cell core during apoptosis and necrosis (option c).
Step-by-step explanation:
The two main destinies of dying cells are apoptosis and necrosis. Apoptosis is a programmed cell death that occurs in normal development when cells are no longer necessary or are genetically damaged. Necrosis, on the other hand, is an accidental death caused by external injury.
Apoptosis differs from necrosis in terms of cell components. In apoptosis, the cell's components are destroyed, while in necrosis, the cell's plasma membrane is lost, leading to the disintegration of the cell.
DNA profiling is possible from supposedly dead cells because the DNA is preserved in the cell core during apoptosis and necrosis. The destruction process in these cell death mechanisms does not always affect the DNA, allowing it to be used for profiling.
Although DNA storage in dead cells may indicate some level of cell survival, it is important to note that dead cells cannot be considered entirely alive. DNA storage in dead cells is likely due to protective mechanisms or delayed cell death.
The fate of the cell core during apoptosis or necrosis depends on the specific cell type and the processes involved. In some cases, the core is destroyed in both apoptosis and necrosis, while in other instances, it may be preserved in necrosis but not apoptosis.
The reliability of DNA profiling from dead cells is unknown. While DNA profiling can still provide accurate and reliable results from dead cells, it is influenced by several factors, including the cause of cell death.
Hence, the answer is option c,b and c.
