Question

29/35 chromatid pairs can be seen, spindle fibers form and nuclear membrane disappears metaphase anaphase prophase telophase

Explanation:

To determine the correct phase of cell division, we analyze each option:

• Metaphase: Chromosomes align at the equator, spindle fibers attach to centromeres. The described events (chromatid pairs visible, spindle fibers form, nuclear membrane disappears) do not match.
• Anaphase: Sister chromatids separate and move to opposite poles. This does not match the given description.
• Prophase: Chromatin condenses into chromatid pairs (chromosomes), spindle fibers form, and the nuclear membrane breaks down. This matches the described events.
• Telophase: Chromosomes decondense, nuclear membranes reform, and cytokinesis begins. This does not match.

Answer:

Prophase (the option labeled "Prophase")
