Which event distinguishes prophase from prometaphase in mitosis?
Understand the Problem
The question is asking about the key event that marks the transition from prophase to prometaphase in mitosis, requiring an understanding of the distinct characteristics of each phase.
Answer
The breakdown of the nuclear envelope distinguishes prophase from prometaphase.
The event that distinguishes prophase from prometaphase in mitosis is the breakdown of the nuclear envelope.
Answer for screen readers
The event that distinguishes prophase from prometaphase in mitosis is the breakdown of the nuclear envelope.
More Information
During prophase, the nuclear envelope is still intact. During prometaphase, the nuclear envelope breaks down into small vesicles.
Tips
A common mistake is confusing prophase and prometaphase. Remembering that the nuclear envelope breaks down during prometaphase can help distinguish the two.
