The document describes the stages of the cell cycle including interphase, replication, and mitosis. During interphase the cell grows and the nucleus replicates its DNA. Mitosis then occurs, dividing the cell into two identical daughter cells through the stages of prophase, metaphase, anaphase and telophase. Cytokinesis follows mitosis, separating the two nuclei and fully dividing the parent cell.

2. 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

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

9. 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

10. 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

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

13. Metaphase The Spindle fibres tug the chromosomes into a line across the middle.

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

17. Telophase The 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.

19. Cytokinesis The 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.
