What happens during prophase of cell division?
Understand the Problem
The question is asking for the events that occur during prophase of cell division, specifically which statement accurately describes that process.
Answer
Chromosomes condense, centrosomes move to opposite sides, nuclear envelope breaks down, and spindle microtubules attach during prophase.
During prophase, chromosomes condense, centrosomes move to opposite sides, and the nuclear envelope breaks down, allowing spindle microtubules to attach.
Answer for screen readers
During prophase, chromosomes condense, centrosomes move to opposite sides, and the nuclear envelope breaks down, allowing spindle microtubules to attach.
More Information
During prophase, the chromatin condenses into visible chromosomes, making it easier for these genetic materials to be separated later. The breakdown of the nuclear envelope is crucial for spindle fibers to engage with chromosomes.
Tips
A common mistake is confusing prophase with metaphase. In metaphase, chromosomes align at the metaphase plate, while in prophase, the main activities include condensation of chromosomes and spindle formation.
