Question

using the pictures of the stages of mitosis, which choice labels: prometaphase

Explanation:

Prometaphase is a stage in mitosis where the nuclear envelope breaks down, and the spindle fibers attach to the chromosomes. In the given options, we need to identify the image that shows these characteristics.

• Option A: Shows two cells, likely cytokinesis (cell division), not prometaphase.
• Option B: Shows chromosomes aligned, which is metaphase.
• Option C: Shows chromatin in the nucleus, likely interphase.
• Option D: Shows chromosomes being pulled apart, anaphase.
• Option E: Shows chromosomes with spindle fibers attached (after nuclear envelope breakdown), which is prometaphase.
• Option F: Shows chromatin in the nucleus, likely interphase.

Answer:

E
