Question

ariana garcia aponte’s practice p.7 mitosis and the cell cycle... during which phase are the chromosome copies, called sister chromatids, pulled apart to opposite sides of the cell?
anaphase
prophase
interphase
metaphase

Explanation:

To solve this, we recall the phases of mitosis:

• Prophase: Chromosomes condense, spindle forms.
• Metaphase: Chromosomes align at the equator.
• Anaphase: Sister chromatids are pulled apart to opposite poles.
• Interphase: Cell grows, replicates DNA (not a mitotic phase for chromatid separation).

So the phase where sister chromatids are pulled apart is anaphase.

Answer:

anaphase
