Review questions for chapter 10
| Question | Answer |
|---|---|
| which is related to a cell's ratio of surface area to volume | cell size, rate of growth, efficiency of cell's transport of oxygen, efficiency of cell's transport of nutrients |
| which family of proteins regulates the timing of the cell cycle in eukaryotes | cyclins |
| what are the phases of mitosis | prophas, anaphase, telophase,metaphase |
| chromatids are attached to each other at the | centromere |
| in the cell cycle, the period between cell divisions is called | interphase |
| a process in which unregulated cell division occurs | cancer |
| a process of cytoplasmic division | cytokinesis |
| series of events that cells go through as they divide and grow | cell cycle |
| the division of the cell nucleus | mitosis |
| the rate at which materials enter and leave the cell's membrane depends on the cell's | surface area |
| the process of cell division results in | two daughter cells |
| pairs of identical chromatids are attached to each other at at an area called the | centromere |
| if a cell has 12 chromosomes, how many chromosones will each of its daughter cells have after mitosis | twelve |
| At the beginning of cell division, a chromosome consists of two | chromatids |
| The phase of mitosis during which chromosomes become visible and the centrioles separate from one another is | prophase |
| the timing of the cell cycle in eukarotic cells is controlled by a group of closely related proteins known as | cyclins |
| in the cell cycle external regulators direct cells to | speed up and slow down the cycle |
| uncontrolled cell division occurs in | cancer |
