DNA replicates.
Homologous chromosomes pair up in the nucleus of the original cell. The nuclear membrane breaks down.
Both daughter cells pinch in the middle. A new nucleus begins to form around both groups of chromosomes.
Both daughter cells divide completely into two daughter cells. This results in four total daughter cells.
Homologous chromosome pairs line up in the center (middle) of the cell.
The cell pinches in the middle. New nuclear membranes form around the two groups of chromosomes.
The nucleus in each daughter cell dissolves (breaks apart) and disappears (cannot be seen).
Homologous chromosome pairs are pulled apart. One chromosome from the pair moves to one side of the cell. The other chromosome moves to the opposite side of the cell.
The chromosomes line up in the center (middle) of each daughter cell.
The original cell divides completely into two daughter cells.
The chromosomes are pulled apart in each daughter cell. Each chromosome is made of two identical chromatids. Each chromatid is pulled to an opposite side of the cell.
