- Hello Students ! Today we are going to be learning the cell cycle.🧬
-
- The first stage of the cell cycle is Interphase! The cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division.
- G phases,S phase,Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.
-
-
- TelophaseDuring telophase, the chromosomes arrive at the cell poles. The mitotic spindle disassembles and the vesicles that contain fragments of the original nuclear membrane assemble around the two sets of chromosomes.
-
- MitosisMitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells. The word "mitosis" means "threads," and it refers to the threadlike appearance of chromosomes as the cell prepares to divide.
- Next on the cell cycle is mitosis!
-
- ProphaseDuring prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes.
- The first stage of mitosis is Prophase! Than the second stage which is Metaphase!
- MetaphaseMetaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible.
- AnaphaseIn anaphase each chromatid pair separates into two identical chromosomes that are pulled to opposite ends of the cell by the spindle fibers.
- The third stage of mitosis is Anaphase! Than the fourth stage which is Telophase!
- CytokinesisDuring cytokinesis, the cytoplasm (the liquid center of the cell that holds the organelles into place) splits into two equal halves, and the cell becomes two daughter cells. After cytokinesis, non-kinetochore microtubules reorganize and disappear into a new cytoskeleton as the cell cycle returns to interphase
- Now lastly,The last stage is Cytokinesis!
