It is crucial that the process of mitosis is error free. this is because otherwise healthy cells can

The right answer is Become cancer cells.

To multiply constantly, cancer cells bypass many regulations of cell proliferation, which leads them to proliferate uncontrollably. These cells have several solutions to prevent senescence.

In a healthy situation, a cell needs growth factors to proliferate. In a cancerous situation, the cancer cell can mutate an oncogene so that it permanently generates proliferation signals, regardless of the presence of growth factors.

For a cell to proliferate, the critical point it must pass through the cell cycle is the restriction point maintained by the Rb protein. Proliferation signals must be sustained to inactivate this control point as the rest of the cell cycle progresses without external stimulation. To proliferate excessively, the cancer cells thus overactivate the cell proliferation signals to pass the restriction point as quickly as possible. They use several strategies to over-activate these signals.

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.
