Interphase before DNA replication

 

 

 

 

 

 

 

 

 

Interphase before DNA replication has chromosomes and a nucleolus inside of the nuclear membrane. Inside the cell there is the nucleus and centrioles. In this phase of interphase, the cell increases in size and makes the proteins and the molecules.

 

Interphase after DNA replication

 

 

 

 

 

 

 

 

 

Interphase after DNA replication has sister chromatids and nucleolus inside the nuclear membrane. Inside the cell there is the nucleus and centrioles. In this phase of interphase, the cell continues to grow and produce proteins and molecules.

 

Early Prophase

 

 

 

 

 

 

 

 

 

In the early prophase, the nuclear membrane and the nucleolus will disappear and spindle fibres will start to grow.

 

Late prophase

 

 

 

 

 

 

 

 

 

In the late prophase, the spindle fibres will fully grow and the centromeres of the sister chromatids will start to be attached to the spindle fibres.

 

Metaphase

 

 

 

 

 

 

 

 

 

In the metaphase, the spindle fibre tugs on the sister chromatids making them align on the middle of the cell.

 

Anaphase

 

 

 

 

 

 

 

 

 

In the anaphase, the spindle fibres will begin to shorten making them pull the sister chromatids apart and move them to the opposite poles of the cell. So the sister chromatids will become separated making them chromosomes again.

 

Telophase

 

 

 

 

 

 

 

 

 

In the telophase, one complete set of chromosomes is at each pole of the cell. The spindle fibres begin to disappear and a nuclear membrane forms around each set of chromosomes. The nucleolus appears in each nucleus. There are two nuclei in one cell, the cell is ready to divide.

 

Cytokinesis

 

 

 

 

 

 

 

 

 

In the cytokinesis or the final stage of the cell cycle, the two nuclei has been separated and has become two daughter cells. These new cells are identical to the original parent cell.
