PATHOLOGY

Detailed explanation-1: -Apoptosis, or programmed cell death, is essential in development and homeostasis in multi‐cellular organisms. It is also an important component of the cellular response to injury. Many cells undergo apoptosis in response to viral infection, with a consequent reduction in the release of progeny virus.

Detailed explanation-2: -Apoptosis can eliminate infected or cancerous cells For instance, this may be the case for cells with DNA damage, pre-cancerous cells, and cells infected by viruses. If these cells undergo apoptosis, the threat to the rest of the organism (such as cancer or spread of a viral infection) is removed.
