LIFE SCIENCE

Detailed explanation-1: -Cells do not live forever, and they will reach a point where they will divide through mitosis, or die through a process called apoptosis. Cancer cells are the exception, these cells do not die and divide uncontrollably as they crowd out healthy, productive cells.

Detailed explanation-2: -Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.

Detailed explanation-3: -To err is human Mistakes during mitosis lead to the production of daughter cells with too many or too few chromosomes, a feature known as aneuploidy.

Detailed explanation-4: -Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators.
