Growth in an what is carefully controlled by regulating the cell cycle? | Organism |
In the cell cycle, external regulators direct cells to do what? | Speed up or Slow down the cycle |
What speed up or slows down the cell cycle? | External regulators |
What is the cell cycle? | Series of events that cells go through as they grow and divide |
What is a series of events that cells go through as they grow and divide? | The cell cycle |
An uncontrolled cell cycle is what? | Cancer |
What is cancer? | An uncontrolled cell cycle |
The timing of the cell cycle in eukaryotic cells is controlled by a group of closely related proteins called what? | Cyclins |
What are cyclins? | A group of closely related proteins which control the timing of the cell cycle. |
How many phases are in the cell cycle? | Five |
There are Five phase in what? | The cell Cycle |
What are the new cells that are formed during mitosis called? | Daughter cells |
What are the daughter cells? | The new cells that are formed during mitosis |
The period of Interphase in which cells do most of their growing. | G1 Phase |
What is the G1 phase? | The period of Interphase in which cells do most of their growing. |
Normal human body cells have how many chromosomes? | 46 |
There are 46 chromosomes in what? | A normal human body |
If a cell has 12 chromosomes, how many chromosomes will each of its daughter cells have after mitosis? | 12 |
If a daughter cells contains 12 chromosomes, how many chromosomes did the cell have before mitosis? | 12 |
What is the last stage in the the cell cycle? | Telophase |
What is the telophase? | The last stage in which new membranes form around the daughter nuclei while the chromosomes disperse and are no longer visible under the light microscope. Cytokinesis or the partitioning of the cell may also begin during this stage. |
What is the longest stage? | Interphase |
What is the interphase? | The first and longest stage of the cell cycle in which the cell is engaged in metabolic activity and performing its duty as part of a tissue. The DNA duplicates during interphase to prepare for mitosis. |
