Metaphase: 7.) In metaphase, chromosomes move to the center of the cell, where they are held in place by kinetochore fibers. 8.) The proof that chromosomes replicate themselves is that since the chromosomes are clearly visible during metaphase, two sister chromatids can be seen that cannot be seen before, meaning that the DNA copies itself and replicates itself into two chromatids. 9.) The fibers that become visible in this phase are kinetochore fibers, that extend from centrosomes, and attach to each sister chromatid. Their purpose is to pull apart the chromatids from the centromeres during anaphase. 10.) The structure that the kinetochore fibers attach to the chromosomes is called the centromeres. Anaphase: 11.) During Anaphase, the pairs of sister chromatids are pulled apart to opposite sides of the cell. 12.) The chromosomes are being directed towards the centrosomes. 13.) The sister chromatids have to move in order for each daughter cell to be genetically identical to the mother cell, and these sister chromatids need to separate in order for the cell to divide evenly. Telophase: 14.) A nuclear envelope and nucleolus begin to reappear during telophase. 15.) From the mother cell, two daughter cells have been formed.

    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.
