Cell cycle

• CELLCYCLE - It is a series of events that leads the cells to duplicate their genetic contents and divide into daughter cells
• The entire cycle is divided into two main stages
• Interphase - it is divided into three stages: G1 phase, S Phase and G2 phase
• M-phase (where M stands for either Meiosis or Mitosis) - The cell undergoes division
• As new cells are produced during cell division (mitosis & meiosis) the cell passes through different stages of development.
• What is this?

  Blue arrow: Interphase

  Yellow: G1 growth

  Orange: S DNA Replicate

  
• Identify the missing

  Purple: G1 growth, preperation for cell division

  Green: mitosis

  Green arrow: cytokenisis

  
• Cytokinesis - The final step of mitosis where the cytoplasm divides to form two separate cells.
• The cell grows and replicates its chromosome to prepare cell division
• It is also a part where the cell is most active metabolically.
• It spends 90% of time in the process
• G1 Phase - The cell at this stage is still young and it undergoes rapid growth
• G1 phase - Organelles are formed
• G1 phase - The longest phase in
• S phase - The DNA doubles at this stage by the process called replication.
• S phase - At the end of this stage, each chromosome is made up of two sister chromatids attached at the centromere.
• G2 phase - Preparation for cell division
• G2 phase - Assembly of proteins, such as microtubules, hollow protein fibers that cause the chromosomes to move during cell division.
