During this stage of mitosis, the chromosomes become attached to the spindle at their kinetochores. Which stage is it?

Understand the Problem

The question is asking to identify which stage of mitosis is characterized by chromosomes attaching to the spindle at their kinetochores. This indicates a focus on cell division processes, especially the specific functions occurring during each phase of mitosis.

More Information

During prometaphase, the nuclear envelope breaks down, allowing spindle fibers to interact with and attach to chromosomes at the kinetochores. This stage is crucial for alignment and segregation of chromosomes during cell division.

Tips

A common mistake is confusing prometaphase with other stages such as prophase or metaphase. Remember, kinetochores are specific structures on chromosomes where spindle fibers attach, which happens during prometaphase.
