Presentation Transcript

    1. Cell Cycle Stages in growth & division G1 Phase S Phase G2 Phase M Phase Cytokinesis

    2. G1 Phase First growth stage Cell increases in size Cell prepares to copy its DNA

    3. Synthesis Phase Copying of all of DNA’s instructions Chromosomes duplicated

    4. G2 Phase Time between DNA synthesis & mitosis Cell continues growing Needed proteins produced

    5. M Phase Cell growth & protein production stop Cell’s energy used to make 2 daughter cells Called mitosis or karyokinesis (nuclear division)

    6. 6

    7. 7 Overall Cancer Incidence and Mortality Trends in U.S.
