"Interphase:", "-longest stage<br /> -Divided into three phases:<br /> Growth and Preparation: Cell grows<br /> Replication: DNA copies itself, makes a “replica," Ensures new cells are identical<br /> Continued Growth and Preparation: Cell continues to grow, makes materials (proteins) for new cells formed during cytokinesis (daughter cells)" "Mitosis- Prophase:", "-the duplicated chromosomes form into an X shape and the nucleolus disappears.<br /> -Spindle fibers begin to form (tiny tube-like structures made of protein)" "Mitosis- Metaphase:", "-Tugging of spindle fibers line up duplicated chromosomes across the middle of the cell" "Mitosis- Anaphase:", "-spindle fibers shorten, contract<br /> -pulls centromere apart, sister chromatids move to opposite ends of cell<br /> -now each is a chromosome" "Mitosis- Telophase:", "-spindle fibers begin to disappear, nuclear membrane forms around each set of chromosomes<br /> -nucleolus appears in each nucleus<br /> -2 nuclei in one cell = READY TO DIVIDE!" "Cytokinesis:", "-final stage, separates two nuclei into two daughter cells, identical to parent<br /> -Animal: cell membrane pinches together, divides cell’s cytoplasm, organelles<br /> -Plant: cell plate forms along the center, divides into two daughter cells."
