The process of mitosis ensures that the daughter chromosomes are separated correctly.

cells undergo a process called the cell cycle. During the G1 phase cells go about their "daily activities". Eventually some internal clue says it needs to divide when it enters the S phase of its life cycle. Druing this time DNA is replicated. Next the cell enters G2 phase when many of its internal organelles are replicated and the cytoplasm expands in prepartion for division. CEll division then occurswhich is divided into the 4 phases of mitosis(nuclear division when the dupicated DNA strands are separated and move to opposite ends of the cell) and cytokinesis in which the cytoplasm and the organelles are split so that both cells now have an equal portion of genetic material and the necessities of other structures to sustain life.

It is process of cell division in non reproductive cells,further the daughter cells chromosomes have a some type of genes as parent cell,the genetic composition remains unchanged,so it only ensures cell multiplication unlikely as happenes in meiosis.
