Chromosomes line up down the middle |
|
|

Keeping internal conditions stable |
|
|
How do skin cells near a cut behave |
They grow and divide until they come in contact with one another |
|
|
How might multinucleated cells come from |
Mitosis has occurred repeatedly without cytokinesid having occurred |
|
|
Explain the role of p53 in growth and division of cells |
Healthy p53 will stop the cell cycle after cells have properly replicated a defect in p53 will allow the cells to multiply chaotically |
|
|
How might a scientist test a cell for cancer if it has not yet formed a tumor |
Culture it in a Petri dish to see if it responds to the signals to regulate the cell cycle |
