Question

Apoptosis is
A)rapid cell division.
B)caused by proto-oncogenes.
C)the change in shape of a cell when it becomes cancerous.
D)programmed cell death.
E)None of these

Accepted Answer

Apoptosis is programmed cell death, which is a process of self-destruction that occurs in cells during normal development and aging. It is highly regulated and involves a series of biochemical events that lead to the controlled dismantling of the cell. It is different from rapid cell division and the change in shape of a cell when it becomes cancerous. While proto-oncogenes play a role in the regulation of cell growth and division, they do not directly cause apoptosis.
