Final answer:
The correct order of events in mitosis is: the kinetochore becomes attached to the mitotic spindle (prometaphase), sister chromatids line up at the metaphase plate (metaphase), sister chromatids separate (anaphase), and the nucleus re-forms and the cell divides (telophase and cytokinesis).
Step-by-step explanation:
Understanding the Order of Events in Mitosis
Mitosis is a critical process in cell division that ensures the daughter cells receive an exact copy of the parent cell's DNA. It consists of several precisely ordered steps: prophase, prometaphase, metaphase, anaphase, and telophase. During prophase, the chromatin condenses into visible chromosomes, and the mitotic spindle begins to form. Prometaphase is marked by the breakdown of the nuclear membrane and the attachment of spindle fibers to the kinetochores of chromosomes. In metaphase, chromosomes align at the metaphase plate. During anaphase, the sister chromatids separate and are pulled to opposite poles of the cell. Finally, in telophase, the nuclear membranes re-form around the separated chromosomes, and the cell prepares to divide, culminating in cytokinesis.
The correct order of events in mitosis according to the options provided would be: The kinetochore becomes attached to the mitotic spindle, sister chromatids line up at the metaphase plate, the sister chromatids separate, and the nucleus re-forms and the cell divides.
