What is a function of centrioles? The main function of the centriole is to help with cell division in animal cells. The centrioles help in the formation of the spindle fibers that separate the chromosomes during cell division (mitosis). What is density dependent inhibition? population growth is curtailed by crowding, predators and competition. In cell biology, it describes the reduction in cell division. What happens during Anaphase? centromeres of sister chromosomes split, sister chromatids now chromosomes are pulled to opposite poles of the cell by kinetochore microtubules. What are spindle fibers? Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. During mitosis, the spindle fibers are called the mitotic spindle. What is the purpose of MPF? M phase promoting factor, is the regulation of the cell cycle. What happens during Telophase? nonkinetochore microtubules elongate the cell. Daughter nuclei begin to form at opposite poles. Chromosomes uncoil, the nuclear envelope reforms and the nucleolus reappears. Usually cytokinesis occurs by the formation of a cell plate in plants or a cleavage furrow in animals. What are kinetochore microtubules? Any of the spindle microtubules that attach to the kinetochores of chromosomes by their plus ends, and maneuver the chromosomes during mitotic or meiotic chromosome segregation. What is cancer? escape the control of cell division, ignore density dependant inhibition, may stop the cell cycle at any point, can divide indefinitely, caused by changes in genes that control cell division. (tumor, benign tumor, malignant tumor). Regarding mitosis and cytokinesis, one difference between higher plants and animals is that in plants…. a CELL PLATE begins to form at telophase, but in animals a CLEAVAGE FURROW is initiated at that stage How do mother cells resemble daughter cells? They are identical copies of the mother cells. What causes lengthening of the cell along the mitotic axis during mitosis? Nonkinetochore microtubules are the ones responsible. These microtubules interdigitate and overlap across the metaphase plate.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
