Mitosis is a process divided into 4 phases: prophase, metaphase, anaphase, and telophase. When mitosis is going to occur, the chromatin in the nucleus become condensed, and the chromosomes become visible. After the DNA is replicated each chromosome is duplicated into 2 daughter cells leaving each with the same number of chromosomes. The 2 daughter cells are identical to each other as well as to the parent cell. The purpose of mitosis is to make new cells, continue humans to grow, repair tissue, and heal cuts, which create new skin. Cancer is uncontrolled mitosis, which results in uncontrolled cell division. If we understand mitosis we may be able to stop cancer.

In the beginning of meiosis the parents cell and chromosomes occur in pairs. Next DNA has been replicated and the chromosomes are duplicated. Each chromosome consists of two chromatids held together at a centromere. The homologous chromosomes come together and line up side by side. In order to produce (offspring) we need meiosis in order to do so.
