What are the stages of the cell cycle?

Interphase and Mitosis make up the cell cycle.Interphase includes 3 phases- G1- Cell growth phase and this is where cell multiply their organelles and their cytoplasms expand;S phase- DNA synthesis phase and this is where the DNA is replicated, producing sister chromatids, attached together by a centromere; G2- The cytoskeleton is dismantled and organelles are duplicated ready for mitosis to begin.Mitosis consists of 4 stages: Prophase, Metaphase, Anaphase and Telophase. In prophase, the chromosomes condense and mitotic spindles begin to form.In metaphase, the chromosomes align at the centre of the metaphase plate and attach to microtubules using the kinetochore.In Anaphase, sister chromatids separate and travel to opposite poles of the cell and are now chromosomes.In Telophase, the spindle disappears and the cell can divide into two separate cells and the cytoplasm separates in a process called cytokinesis. The chromosomes also decondense.
