Direction: Label the diagram below with the following labels: Anaphase Metaphase Cell division (M Phase) Prophase Cytokinesis Telophase G1 –cell grows Interphase G2- prepares for mitosis Mitosis S-DNA replication The Cell Cycle Coloring Worksheet Then on the diagram, lightly color the G1 phase light GREEN, the S phase YELLOW, the G2 phase light BLUE, and the stages of mitosis VIOLET. Color the arrows indicating all of the interphases in BLUE. Color the part of the arrow indicating mitosis PURPLE and the part of the arrow indicating cytokinesis light VIOLET. Checkpoint is a critical control point in the Cell Cycle where ‘stop’ and ‘go-ahead’ The three major checkpoints are found in the G1, G2, and M phases of the Cell Cycle. The G1 Checkpoint (the Restriction Point) ensures that the cell is large enough to divide and that enough nutrients are available to support the resulting daughter cells. If a cell receives a ‘go-ahead’ signal at the G1 checkpoint, it will usually continue with the Cell Cycle. NOTE: If the cell does not receive the ‘go-ahead’ signal, it will exit the Cell Cycle and switch to a non-dividing state called G0. Most cells in the human body are in the G0 phase. The G2 Checkpoint ensures that DNA replication in S phase has been successfully completed. The Metaphase Checkpoint ensures that all of the chromosomes are attached to the mitotic spindle by a kinetochore. is a disc-shaped protein structure associated with duplicated chromatids in eukaryotic cells where the spindle fibers attach during cell division to pull sister chromatids apart. ✓ Have you experienced to get cuts and bruises and few days after, they are healing? ✓ Have you noticed your worn- out cells on the sole of your feet are being replaced? Your cells throughout your body are growing, dividing and repairing through the process called CELL DIVISION which is a fundamental process in the human body. which involves the distribution of identical genetic material or DNA to two daughter cells. There are two ways by which cells increase in number: 1. Mitosis 2. Meiosis  PROPHASE The chromosomes (genetic material) condense (coil tightly) and the nucleolus disappears.  METAPHASE The chromosomes align in the Centre of the cell and attach to microtubules in preparation to split apart.  ANAPHASE Chromatids separate and move to opposite ends of the cell. This stage ensures that each cell contains identical chromosomes after splitting.  TELOPHASE Two nuclei form around each set of chromosomes. Chromosomes decondense and the cells begin to split from each other. Telophase is followed by cytokinesis, which denotes the division of the cytoplasm to form two daughter cells. Thus, it marks the completion of cell division.
