Zak Murdock Pd. 1 11/30/07 Video Questions 1) Mitosis consists of a single nucleus giving rise to two nuclei that are genetic clones of one another as well as of the parent nucleus. It ensures that the cells multiple chromosomes are accurately distributed to the daughter nuclei. Mitosis consists of a series of separate events known as prophase, prometaphase, metaphase, anaphase, and telophase. Prophase is the beginning of mitosis where the individual chromatids first become visible. Although they are visible they are still held together at the centromere. Along with the chromatids becoming visible, the spindle forms. The spindle is made up of two types of microtubules, polar microtubules and kinetochore microtubules. It serves as a structure for the chromosomes to attach to as well as framework keeping the two poles apart. In the late stages of prophase, specialized three layered structures known as kinetochores develop, which are very important to chromosome movement. Prometaphase is the first of three phases of mitosis in which chromosomes begin to move.
