Practice Question

In which phase of mitosis do sister chromatids separate?

Answer Choices:

Correct Answer:

Anaphase

Rationale:

🖊️ During anaphase of mitosis, the sister chromatids are pulled apart toward opposite poles of the cell.

🖊️ The separation occurs as the spindle fibers shorten, ensuring each daughter cell receives an identical set of chromosomes.

🖊️ This is one of the most critical steps in mitosis for maintaining genetic stability.

🖊️ In contrast, metaphase aligns chromosomes at the equatorial plate, while telophase reforms nuclear membranes.

🖊️ Prophase is when chromosomes condense, but separation only occurs in anaphase.
