Steps of mitosis

interphase Interphase is when the cell is preparing for mitosis. In this stage the cell doubles in size.

Prophase

Prophase is when the cell DNA start to windup and form x shaped chromosomes. The nucleus starts to break and stretch.

The nucleus breaks and all the chromosomes spill out. The cell will now start to form the spindle fibres and move them around in the cell.

Prometaphase

metaphase In this phase the cell’s spindle

fibre extends itself and attaches to the chromosomes. The chromosomes form a line in the center of the cell.

AnaphaseIn this phase the cell starts to pull the chromosomes apart and split into two cells. The chromosomes split in half. One half of each chromosome go to different sides of the cell.

TELOPHASE

The spindle fibres start to rip the cell it too two pieces. The cell is almost done. The cell is now starting to moves its organelles.

The cell has finally split apart. The cell is still together sharing information and organelles. The spindle fibres are starting to split apart and fuse back into the cell. The nucleus starts to reform.

cytokinesis

interphase

The cell has finally split and is starting the cycle all over again.

Now to show what it looks like without interruptions click on the arrow in the bottom corner really fast.
