Spindle fibers attach to kinetochores of chromosomes during

Question

Spindle fibers attach to kinetochores of chromosomes during:

Option 2: Metaphase

Explanation:

Let's review the stages of mitosis:

Prophase:

During prophase, the chromatin condenses into chromosomes, and the mitotic spindle begins to form. However, the spindle fibers do not attach to the kinetochores of the chromosomes in this stage.

Metaphase:

During metaphase, the spindle fibers from opposite poles of the cell attach to the kinetochores of the chromosomes. The chromosomes then align along the metaphase plate (the equator of the cell).

Anaphase:

During anaphase, the sister chromatids separate and are pulled to opposite poles of the cell by the spindle fibers.

Telophase:

During telophase, the chromosomes decondense, the nuclear envelope reforms, and the cell prepares for cytokinesis. The spindle fibers disappear.

Therefore, the spindle fibers attach to the kinetochores of chromosomes during metaphase.
