Prometaphase Two

Prometaphase II is a stage of meiosis II when the nuclear envelope breaks down

Microtubules extend from the centrioles, forming a spindle

Kinetochores monitor attachment status and tension to activate checkpoints and error-correction mechanisms. 

and the spindle is fully formed. 

During this stage, each sister chromatid forms a kinetochore that attaches to microtubules from opposite poles

Microtubules extend from the centrioles, forming a spindle. 

Nuclear envelope breakdown: The nuclear membrane breaks down into small vesicles, allowing spindle microtubules to access the cell's genetic material

Kinetochore formation: A protein structure called a kinetochore forms around the centromere, which is the central point of the sister chromatids

Microtubule attachment: Microtubules from the centrosomes at the poles of the spindle attach to the kinetochores

Chromosome movement: The chromosomes move back and forth until they align on the metaphase plate

in the center of the spindle
