Dr. Potter MITOSIS When individual cells reproduce, they do so by dividing into 2 daughter cells. In order for each daughter cell to have a complete set of genetic information so it can live and reproduce, then cell division must be preceded by semiconservative DNA replication. This process of cell reproduction must be carried out in a precise, orderly manner so that each daughter cell obtains complete genetic information, as well as the cytoplasmic contents it needs. Cell division includes mitosis (karyokinesis) which refers to nuclear division and cytokinesis which refers to cytoplasmic division. Both processes must occur. The result is 2 genetically identical daughter cells. This is called asexual reproduction and there is no genetic variation . In order to understand this process, you will need to study the diagrams in the text. The cell cycle is a description of the life stages of a re- producing cell. The growing phase is interphase and consist of 2 growth phases, G1 and G2, separated by the S phase (DNA replication). What are
