Prophase The genetic material inside the nucleus condenses and the chaplicat the first stage of microsis called prophina.the huginning of prophase, the aister thtomatids.strands of condonsed chromos become visiolo. They are attach ind to each other at a poin: cailed the centromane in the cytoplasm, twu tiny organ.alles. called willinglast are invelved in devoloping spindle fibers that span across the cal Metaphase During bratashasi the spincle floers move the centromeros of the duplicated chromason ins to the center of the cell. These spindle fibers are connected to the two near the contrioles and are ready to separate the sister chromarids. Anaphase During anaphase the chromosomes separate and move along the spincle fibers to opposite ends of the cell. Anaphase ends when the Sister chromatids, now cansidered individual chromosomes, are completely separated into two groups and the spincile fibers have almost disappeared. Telophase During Eelophiase, the chromosomes, which were distinct and condensed, begin to spread out into a tangle of chromatin.This is the final stage of mitosis.The nuclear envelope is reconstructed and the nucleolus becomes visible in each new cell. Cytokinesis QKEY QUESTION How do daughter cells split apart after mitosis? In plants, cytokinesis separates the cells by forming a cell plate between the divided nuclei In animals, cytokinesis draws the membrane inward to separate the cells. During the M phase of the cell cycle,mitosis forms two nuclei, each with a complete set of the DNA. The last segment of the Mphase is cytokinesis. Cytokinesis completes the process of cell division by dividing one cell into two. Cytokinesis in Animal Cells The cell membrane is drawn inward and pinched into two new daughter cells Each cell contains the new nucleus formed during mitosis and an equal mount of cytoplasm. ytokinesis in Plants Because of the rigid cell wall outside.the cell membrane in plant cells, pinching from outside inward cannot occur A.cell plate forms halfway ween the two nuclei and with the existing cell membranes. A new cell wall then to separate the two daughter cells. by Sawas Learning Compa BOILD Voenbulary prophase first and longes? phaie ol mitos in which the ganetic material insido the nucious condenses and the chrom osomes become visibin chromatid one of two identical "sister"party of o duplicated chromosome centromere region of chromosome where the two sister chromat ds attach cell that helps to organize coll contriole structure is an animal division which the chromesomes line up metaphase phase of mitosis in across the center of the cell anaphase phase of mitosis in which t e chromosomes separate and move to opposite ands of the cell in which the distinct individual telophase phase of mitosis chromosomes begin to spread out into a tangle of chromatin Prefixes In biology, the prefix telo-means "enci" or "completion."
