DNA e double s om helix m o hr o te dc pl i ca du coils sister centromere chromatids nucleosome supercoils histone proteins Prokaryotic Cell Cycle Prokaryotes undergo binary fission. Why does the cell duplicate its DNA? What would happen if the cell membrane did not indent and pinch off? Is binary fission an example of sexual or asexual reproduction? Eukaryotic Cell Cycle Eukaryotic cells have a more complex cell cycle than prokaryotic cells. Do you think that cells get smaller with each successive cell division? M Phase Cell division occurs during M phase. Describe the importance of the cell cycle to the growth of organisms. Name of the Mitotic Phase. Description. Prophase The nucleus condenses and chromosomes become visible. The spindle begins to form. Metaphase Chromosomes line up at the center of the cell. centrioles chromatid centromere chromosome Anaphase: Think about the importance of this step inmove Chromosomes mitosis toward opposite poles. individual chromosomes What would happen if one of the duplicated chromosomes did not separate correctly during anaphase? Telophase The cell begins to divide into daughter cells. nuclear envelopes re-forming Cytokinesis In animal cells, the cell membrane pinches in the center to form two daughter cells. Describe how cytokinesis differs in plant and animal cells Mitosis Overview List and describe the phases of mitosis. Interphase Cytokinesis 1 Prophase 4 Telophase 2 Metaphase 3 Anaphase Exit Questions: 1. What must happen during interphase for a cell to be able to divide? 2. Identify each stage of mitosis and describe what happens at each stage, beginning with stage 1. 3. Describe what happens during cytokinesis.
