Interphase is the synthesis of biological molecules including DNA and duplicated DNA with associated proteins. These comprise the chromatin that begin to condense toward the end of this phase, but are not yet visible. The nucleoplasm has a uniform grainy appearance. Prophase is when the chromatin condenses into the more distinct elongate strands early in prophase. Also nucleoli and the nuclear membrane begin to disappear. The mitotic spindles take formation at opposing ends of the cell. The chromatin is visible, but only in threads. Metaphase is the most distinctive of all stages of mitosis, because it is characterized by the regular arrangement of chromosomes at a central region called the metaphase plate. Now Anaphase beings as duplicate chromosomes separate, moving to opposite poles of the cell. Telophase is marked by the formation of a nuclear membrane around two daughter nuclei. Also chromosomes begin uncoiling and less distinct. Cytokinesis begins at this stage, which is shown with the development of a cell plate in plants cells. Hypothesis: Prophase will be the phase that the cells spend the most time in, because so many things are occurring as opposed to other cells. Chromatins
