Question

A cell that is dividing too rapidly may have lost its ability to enter which part of the cell cycle?

Answer 1

A cell that is dividing too rapidly may have lost its ability to enter apoptosis cycle of cell. Now let's have a closer insight of what it is generally what happens in case of multicellular organisms is the cells dies in a programmed manner and this process has been named apoptosis which is derived from a Greek term that means falling off. The root cause behind this often death of the cells is the morphology that means the diversity in biochemical events. In fact you will be surprised to know in an average human everyday near about 70 bilion cells dies because of apoptosis.
The worst part is it cannot be regulated at all once it has started then it will keep going that is the biggest fatal factor of this cell cycle.
