This question-specific review guide is tied to the answer reasoning for a PracticeTestVault item. Use it after you answer the question so the review stays focused on what the prompt actually tested.
What this question is testing
Objective: Biology
Prompt focus: During which phase of mitosis do sister chromatids separate and move toward opposite poles of the cell?
Why the correct answer works
Anaphase
Anaphase is defined by the separation of sister chromatids toward opposite poles.
Why the tempting wrong answer fails
In metaphase, chromosomes align at the cell's equator but remain joined as sister chromatids.
Plain-language takeaway
In anaphase, the cohesion holding sister chromatids together is cleaved, and spindle fibers pull the separated chromatids toward opposite poles of the cell.
Simple analogy
Think of biology like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.
How to review it before a retake
- Underline the command word and name what the question is asking before rereading the choices.
- Compare the correct answer against the closest distractor and write the exact detail that separates them.
- Retest this objective with a fresh question without looking at the rationale first.
