As a cell gets larger, what kind of crisis might occur (related to dna)

It is important that the surface area to the volume ratio gets smaller as the cell gets larger.Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function.
