Can anyone help me with this? Thank you.
Lab 13. Mitosis and Meiosis Purpose The purpose of this lab is to understand the process of mitosis and melosis in animal and plant cells. Learning Objectives After completing this lab, you will be able to: 1. Describe the stages of mitosis. 2. Identify the stages of mitosis in an onion root or whitefish blastula using a light microscope. 3. Describe how cytokinesis differs in plant vs. animal cells. 4. Name and...

1. Damaged DNA is discovered during the G1 checkpoint. How does p53 react, and what are the possible results? 2. If S phase checkpoints detect nucleotides deficit, what happens to the dividing cell and the cell cycle? 3. What three conditions may be detected during the G2 checkpoints, and what are the two possible results if there is inadequate DNA or spindle fibers? 4. What two conditions are checked during the metaphase checkpoint? What happens if the cell “passes” the...
