Which of the following is FALSE about mitotic cell division and mitosis? O A. Mitotic cell division is 6 stages: Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis while mitosis is 4 stages: Prophase, Metaphase, Anaphase, Telophase. O B. The terms mitotic cell division and mitosis are the same and they can be used interchangeably to refer to cells dividing to make more cells. O C.A mitotic cell division includes mitosis and mitosis is part of a mitotic cell division. O D. During mitotic cell division, 1 cell divides into 2 cells and during mitosis, 1 nucleus divides into 2 nuclei.
Speculate about the following details of mitosis. 1. Why do chromosomes need to condense during mitosis? 2. Why does the nuclear membrane need to break down at the beginning of prometaphase? 3. Why do chromosomes congress (migrate) toward the metaphase plate during metaphase, and what forces keep the chromosomes there until anaphase begins? 4. What would happen if one kinetochore of one chromosome failed to attach to the spindle and the cell entered anaphase? In a general sense, how do cells normally prevent this situation? 5. During late anaphase and telophase, animal cells elongate to aid the eventual separation of the two daughter cells in cytokinesis. This elongation can occur even in cell suspensions, where different cells do not come into contact. Are the forces that elongate the cell likely to be pushing forces or pulling forces, and where do these forces come from?

Why do u think that is? 3) why would a cell ever want to destroy itself? 4) how long does a cell live before it undergoes mitosis? 5) if cells can constantly replace themselves, why is a heart attack (which kills cardiac muscle cells) so devastating? 6) what type of cells never undergo mitosis? 7) what makes stem cells particularly interesting to researchers? 8) how might stem cells be used to repair brain or heart damage, even though these cells do not undergo mitosis? 9) why do you think beauty experts would also be interested in stem cells? 10) what is the connection between cancer and mitosis? 11) why is it so difficult for your body to battle cancer? 12) why does you hair fall out of the chemotherapy?
1.) Some of the events that occur during mitosis are as follows: 1. separation of sister chromatids to opposite poles 2. condensation of chromatin into compact chromosomes 3. alignment of chromosomes along the cell equator 4. reappearance of nuclear membrane Using the numbers above, match the above-mentioned events occurring during mitosis with the stages in which they occur. Prophase _____ Metaphase _____ Anaphase _____ Telophase 2.) Four different phases that occur during the mitotic phase of cell cycle are as follows: 1. prophase 2. telophase 3. anaphase 4. metaphase The correct order in which phases of the mitotic division occur after G2 phase is __________, _____________, ___________ and ___________.
Normal events in mitosis gives rise to daughter cells with exactly the same chromosome number and genetic material. What may be expected to happen chromosomally and genetically to: 1. an unfertilized egg that undergoes mitosis, but fails to undergo cytokinesis? 2. a cell with a chromosome that lost its centromere? 3. a cell with a chromosome that contains two centromeres?
Q1: Do all cells in an organism enter each stage of mitosis at the same time? (Hint: See image of onion root tip at far left in the ﬁgure.) Q2: What happens between the end of interphase and early prophase that changes the appearance of the chromosomes? Q3: Explain in your own words the role of the mitotic spindle in mitosis.
The phases of mitosis are shown in Figure 6.4. Mitosis is the type of nuclear division that occurs when an animal or plant grows larger and when injury heals. Two daughter cells result because there is only one round of division, and it keeps the chromosome number constant (same as the parent cell). The prophase cell in Figure 6.4 has the same number of chromosomes as the telophase nuclei in Figure 6.4. Explain the different appearance of the chromosomes.
