Cindy s. malone, phd, california state university northridge. The life cycle of a cell culminates in division starting with asking by examining. Cells arise through the division of preexisting cells. There are two types of cell division: Both forms of cell division are accompanied by cytokinesis. The cytoplasm of the cell divides into two distinct daughter cells. Daughter cells have half the amount of genetic material as the parent cell. The production of all other cell types referred to as somatic cells. Genetic material is copied and then divided equally. Daughter cells are genetically identical to the parent cell. Mitosis and cytokinesis are responsible for three key events in multicellular eukaryotes: growth, wound repair, asexual reproduction. A gene is a section of dna that encodes a specific. Contain a single long double helix of deoxyribonucleic acid (dna) The purpose of mitosis is to distribute chromosomes to daughter cells during cell division.
