Question

during this phase of cell division, the chromosomes uncoil, the nuclear membrane forms, and cytokinesis occurs.

○ interphase
○ telophase
○ metaphase
○ anaphase
○ prophase

Explanation:

To solve this, we analyze each phase of cell division:

• Interphase: Cell grows, replicates DNA, not the phase with the described events.
• Telophase: In mitosis/meiosis, chromosomes uncoil (become chromatin), nuclear membrane reforms, and cytokinesis (cell division) occurs. This matches the description.
• Metaphase: Chromosomes align at the equator, no uncoiling or nuclear membrane formation here.
• Anaphase: Sister chromatids separate and move to poles, not the events described.
• Prophase: Chromosomes condense, nuclear membrane breaks down, opposite of the described events.

Answer:

B. telophase
