2. Cell Division: Mitosis Object:Object: To study the various stages in mitotic division

3. In eukaryotes, cell division occurs in two major stages.In eukaryotes, cell division occurs in two major stages. The first stage, division of the cell nucleus, is called mitosis.The first stage, division of the cell nucleus, is called mitosis. The second stage, division of the cell cytoplasm, is called cytokinesis.The second stage, division of the cell cytoplasm, is called cytokinesis. Cell Division

4. Chromosomes Genetic information is passed from one generation to the next on chromosomes.Genetic information is passed from one generation to the next on chromosomes. Before cell division, each chromosome is duplicated, or copied.Before cell division, each chromosome is duplicated, or copied.

5. Chromosomes Each chromosome consists of two identical “ sister ” chromatids.Each chromosome consists of two identical “ sister ” chromatids. Each pair of chromatids is attached at an area called the centromere.Each pair of chromatids is attached at an area called the centromere. Sister chromatids Centromere
