What happens in prophase 1? |
Double stranded chromosomes and spindle fibers appear. The nuclear membrane and the nucleolus disappear. Like chromosomes come together in matching pairs. |
|
|
What happens in metaphase 1? |
The pairs of chromosomes line up in the center of the cell. Their centromeres become attatched to the spindle fibers. |
|
|
What happens in anaphase 1? |
Each double stranded chromosome seperates from its matching chromosome. Each one is pulled to opposite ends of the cell. |
|
|
What happens in telophase 1? |
The cytoplasm divides and two cells form. Each chromosome is still double stranded. |
|
|
What happens in prophase 2? |
The double stranded chromosomes and spindle fiber reappear in each new cell. |
|
|
What happens in metaphase 2? |
The double stranded chromosomes move to the center of the cell. There, the centromeres attach to spindle fibers. |
|
|
What happens in anaphase 2? |
The centromere divides, and the two strands of each chromosome seperate and move to opposite ends of the cell. |
|
|
What happens in telophase 2? |
The spindle fibers disappear, and a nuclear membrane forms around the chromosomes at each end of the cell. Each nucleus contains only half the number of chromosomes that were in the original nucleus. |
|
|
What happens when meiosis 2 is finished? |
The cytoplasm divides. |
