2. Interphase Interphase is the first step of cell cycle The cell grows and carries out life functions The nucleus makes copy’s of its DNA As the grows it has to make more proteins and molecules to make the cell properly function
5. Mitosis Mitosis is the second step of the cell cycle The nucleus divides into 2 equal parts , each have equal amount of DNA There are 4 steps of Mitosis, in order: Prophase, Metaphase, Anaphase, Telaphase
6. Early Prophase Duplicated Chromosomes form an “x” shape chromosome, the Nucleus will disappear and nuclear membrane starts to die down, the spindle fibres start to appear
7. Late Prophase Spindle fibres are fully visible and the “x” chromosomes attach onto the spindle fibres, Nuclear membrane is now gone
8. Metaphase The spindle fibres pull tight making the “x” chromosomes form a straight line across
9. Anaphase Spindle fibres begin to contract pulling the centromeres apart, making the sister chromatints pull apart , after this each sister chromatints is now considered a chromosome
10. Telaphase Telaphase is the final step of Mitosis, here the once used to be one cell is now splitting into 2 cells, the chromosomes are at each end of the poles and there are 2 nuclei in one cell, also the nuclear membrane reappears around each chromosome
11. Cytokinesis In the final stage of the cell cycle, Cytokinesis pulls apart the once used to be one cell into 2, these 2 cells are called sister cells and are similar to the original cell (parent cell), This all happens when the cell membrane pinches together and releases the cytoplasm and organelles .
