- What is the difference between Mitosis and Meiosis cell division? What happens at each stage? When does the body need to undergo Mitosis? What type of human cells goes through Mitosis? When does the body go through Meiosis? What type of human cells go through Meiosis?arrow_forwardBoth Mitosis and Meiosis are nuclear divisions, but they occur for different reasons. What is each process “trying to achieve?”arrow_forwardWhat is the difference between mitosis and Meiosis?arrow_forward
- How does the number of chromosomes in the original cell of mitosis compare with the two daughter cells at end mitosis?arrow_forwardDoes resulting daughter cells in mitosis and meiosis will have identical features with their parent cell? yes or no? Why? Does Interphase prepare the parent cell for division by means of cell growth and synthesis? yes or no? Why? Does the number of chromosomes found in the daughter cells after mitosis and meiosis will be the same as that of the parent cell? yes or no? Why?arrow_forwardA cell has 8 chromosomes in metaphase II of meiosis. How many chromosomes and DNA molecules will be present per cell in this same organism at Prophase of mitosis?arrow_forward
- What are the key differences between mitosis and meiosis?arrow_forwardThe first difference between mitosis and meiosis occurs after the DNA has been duplicated, when prophase begins. What do you notice that is different between mitosis and meiosis during prophase?arrow_forwardA cell has 8 chromosomes in metaphase II of meiosis. How many chromosomes and DNA molecules will be present per cell in this same organism at After cytokinesis that follows mitosis ?arrow_forward
- How are the chromosomes lining up in meiosis differently from mitosis?arrow_forwardHow does mitosis maintain 46 chromosomes in daughter cells, while meiosis reduces the number to 23 in the daughter cells?arrow_forwardA cell has 8 chromosomes in metaphase II of meiosis.
