What cells have lost their normal ability to regulate the cell cycle?
Cancer
How does a cell regulate the cell cycle?
The chemicals that regulate the cell cycle are called cyclins. They work by controlling the timing of the cell cycle in eukaryotic cells.
What controls the rate at which cells divide?
cyclins regulate the timing of the cell cycle in eukaryotic cells,cancer cells do not respond to the signals that regulate the growth of most cells.
When cells fail to respond to the signals that regulate the cell cycle of most cells they form?
They form cancers.
What is one of a family of closely related proteins that regulate the cell cycle in eukaryotic cells?
CYCLIN

Protein known as regulate the timing of the cell cycle in eukaryotic cells?
Cyclins
Proteins called growth factors regulate the timing of the cell cycle in eukaryotic cells?
no

CYCLIN
What is the protein that regulate the timing of the cell cycle in eukaryotic cells known as?
CDK. Cyclin dependent kinases.
What is the difference between cancer cells and normal cells?
Cancer cells normally have a defect in their receptor proteins on the membrane. There are several growth receptors on the surface of cells, and if one of them is faulty, cancer may form. The cancerous mass will continue to divide if there is no negative feedback from the cells surrounding it. In addtition to not being able to receive normal signals that regulate the cell cycle, cancer cells do not stop dividing when growth factors are depleted, simply put cancer cells don't require nutrients to grow, however they may still receive nutrients. As long as a cancer cell is provided with nutrients they may grow indefinately until some random point in the cycle where they may stop, rather then stopping at checkpoints in the normal cell cycle, making them somewhat "immortal". These are the most common differences in cancer cells and normal cells.
What are two ways that cell division is regulated in healthy cells?
internal and external factors regulate the cell cycle
