WebExplain how changes in p53 activity may affect cell cycle control. P53 protein contains four units, which plays an important piece of cell control. Normal cells have a low level of p53 protein, but damage to DNA or other acts can increase p proteins. A person with defective p53 may suffer from abnormal cell growth which can result in cancer WebProphase in an onion root. Metaphase in an onion root. Anaphase in an onion root.

WebCell Cycle Virtual Lab. Identify interphase and the different phases of mitosis by looking at onion cells in a virtual lab and under the microscope. Create a graph to show how much time a cell spends in each phase of the cell cycle. Determine which phase of the cell cycle is the longest and which phase is the shortest. WebAug 2, 2024 · The cell cycle. Figure 1 – Representation of the phases of the cell cycle: gap phase 1, synthesis phase, gap phase 2, and mitosis. The cell cycle can roughly be separated into 2 parts: interphase and mitosis. The mitotic phase is the shortest part of the cell cycle. The rest of the cell cycle, interphase, accounts for about 90% of the cell cycle. WebDec 3, 2007 · ReguJation of the cell cycle .
