p.7 mitosis and the cell cycle
telophase

mitosis
during which phase do chromosomes form and the pairs of centrioles move toward opposite sides of the cell?
metaphase
interphase
anaphase
prophase

Explanation:

To solve this, we analyze each phase:

• Metaphase: Chromosomes align at the cell equator, centrioles are already at poles. Eliminate.
• Interphase: Cell grows, replicates DNA; chromosomes are uncondensed, centrioles replicate but don't move to poles. Eliminate.
• Anaphase: Sister chromatids separate and move to opposite poles; chromosomes are already formed. Eliminate.
• Prophase: Chromatin condenses into chromosomes, and centriole pairs (in animal cells) move to opposite poles as the spindle apparatus forms. This matches the description.

Answer:

prophase (the option with text "prophase")
