What are the part of the cell cycle?

Answer 1

The cell cycle starts of in interphase. In interphase there is three substages. They are G1, S, and G2. In G1 or Gap 1, the cell grows and performs normal functions. In S or Synthesis, the DNA is replicated. In G2 or Gap 2, the cell prepares for the next stage which is mitosis. Interphase is the longest stage. In mitosis, the cell's nucleus and nuclear material divide. Mitosis had four substages to it. The first is prophase which is when the cell's chromatin tightens, or condenses into chromosomes. Then is metaphase which is when the sister chromatids are pulled by motor proteins on the spindle apparatus to the equator or middle of the cell. Sister chromatids are structures that contain identical copies of DNA and are half of a chromosome. Two sister chromatids make up a X shap[ed figure called a chromosome. After metaphase is ananphase, which is when sister chromatids are split and being puled to the poles of the cell. Telophase, which is the last stage in mitosis, is when the chromosomes have reached the poles and the chromosomes begin to relax, or decondense. The last stage in the cell cycle is cytokinesis. In cytokinesis, the cell's cytoplasm divide, creating a new cell. Cytokinesis different in plant and animal cells. In animal cells, cytokinesis begins with a furrow that pinches the cell and eventually splits the two cells apart. Plant cells build a cell plate that divides the cell into the two daughter cells.
