Which of the following types of epithelial tissue line the interior of blood vessels? Which of the following is a unicellular gland associated with mucus production? Which of the following apical epithelial cell structures functions in the movement of materials across the surface of the cell?
During prophase and metaphase of mitosis, each chromosome exists in the above state. For humans, this means that during prophase and metaphase of mitosis, a human will have 46 chromosomes, but 92 chromatids (again, remember that there are 92 chromatids because the original 46 chromosomes were duplicated during S phase of interphase).
Answer Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. These phases occur in this strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase. The mitotic phase is a relatively short period of the cell cycle.
happens in each phase. See page 231 of your text for the labeled figure. G1: “First Gap” The first part of interphase S: “Synthesis” When the chromosomes duplicate G2: “Second Gap” The last part of interphase M: In the M phase, mitosis distributes the daughter chromosomes to daughter nuclei, and cytokinesis
