Which of the following accurately describes the events occurring during mitotic prophase?

During mitotic prophase, one of the key events is the movement of centrioles to opposite poles of the cell, which is crucial for the formation of the mitotic spindle. As the centrioles migrate, the spindle fibers start to form between them. These microtubules are essential for the eventual separation of the sister chromatids during mitosis. Furthermore, during this phase, the chromatin condenses into well-defined chromosomes, making it easier to align and separate them in the subsequent phases of mitosis.

The process ensures that each daughter cell will receive an identical set of chromosomes. By establishing the spindle apparatus and positioning the centrioles correctly, the cell prepares itself for the next stages of mitosis, where the chromosomes will align and ultimately be pulled apart.
