MitosisFlipbookBy Tyler KnollOctober, 27th, 2009

A stage in the cell cycle in which the cell grows and carries out it’s functions. Also the nucleus makes a copy of it’s DNA through a process called replication.Interphase

During the interphase the nucleus makes a copy of it’s DNA. Also during replication the DNA ladder steps break down.Replication

In this stage the nucleus of the cell divides into two equal parts. In these parts each part has a copy of the DNA. Mitosis also has stages: prophase, metaphase, anaphase and telophase.Mitosis

In this stage the duplicated chromosomes form into an x- shaped structure and the nucleolus disappears. Also the Spindle Fibres begin to appear.Early Prophase

The spindle fibres complete forming. The chromosomes attach to the spindle fibres and the nuclear membrane disappear.Late Prophase

MetaphaseThe Spindle fibres tug the chromosomes into a line across the middle.

AnaphaseThe spindle fibres contract and shorten which allows the centromeres to break apart moving the sister chromosomes to opposite poles in the cell.

TelophaseThe final stage in Mitosis. In this stage the spindle fibres disappear. At the same time a nuclear membrane forms around each set of chromosomes and a nucleolus appears within each nucleus.

CytokinesisThe final stage in the cell cycle. In this stage the two nuclei divide into two identical daughter cells which are identical to the parent cell.
