Work Step by Step

Before a cell undergoes cell division, it must make sure that its genetic material is duplicated. Each daughter cell must receive an exact copy of the genetic material of the parent cell. If not, detrimental effects will occur in daughter cells that do not have a faithful copy of the parent cell's genetic material. Option b. is not correct because a cell must increase in volume before it can undergo cell division. Option c. is also incorrect because an increase in chromosomes does not necessarily mean that all the genetic material has been successfully duplicated to produce two exact copies of the genetic material. Option d. is incorrect because organelles must be multiplied before there are enough to be divided between two daughter cells. The number of organelles should increase, not decrease.
