Question

in which phase of mitosis do the chromosomes pull apart
prophase
anaphase
metaphase
telophase

Explanation:

To determine the phase of mitosis where chromosomes pull apart, we recall the stages of mitosis:

• Prophase: Chromosomes condense, spindle forms.
• Metaphase: Chromosomes align at the equator.
• Anaphase: Sister chromatids (chromosomes) are pulled apart to opposite poles by spindle fibers.
• Telophase: Chromosomes decondense, nuclei reform.

Thus, chromosomes pull apart in Anaphase.

Answer:

B. Anaphase
