Cell Cycle Summary
The cell cycle has four main stages that are called: Gap 1, synthesis, Gap 2, and mitosis/cytokinesis.
-(G1) Gap 1 is where cells do their normal functions and have normal growth. At this stage more organelles are reproduced and the volume size of chloroplast is increased. Also protein makes the cell grow immensely during Gap 1 about doubling the cells size. This is very important to grow normally so the cell can be healthy, continue to function properly, and to make healthy cells.
-(S) Synthesis means "combination or composition" In this step the cell puts together, or synthesizes a copy of its nuclear DNA. This is very important because at the end the two cells that were once one cell will have a copy of the DNA. If this step did not take place they would not both have a copy. The cells makes another organelle and another set of DNA so when the cell splits both of the cells will have what it needs to be healthy and function properly.
-(G2) Gap 2 is where the cells to things similar to Gap 1. They carry out their normal functions and continue to grow. It will also produce new proteins. Nothing special occurs in the part of the cell cycle and if the cell is healthy it will advance to the next stage of Mitosis. At the very end of this stage there is a checkpoint to see if the cell is healthy enough to go in Mitosis and split. If the checkpoint did not happen and the cell was to be unhealthy the cell would make more and more unhealthy cells which is not wanted.
-(M) Cell growth and the production of proteins stop in this phase. All of the energy that the cell has is concentrated on the division of the cell. The actual process of mitosis is much shorter than interphase and it only takes from one to two hours to complete. There are two parts of this stage, and they are mitosis where the M comes from and cytokinesis. Mitosis is the part when the cell nucleus and the DNA inside split. Cytokinesis is the division of the rest of the contents within the cell, the cytoplasm.
