By injecting a protein found from a cell in mitosis into a non-dividing cell, a mitotic spindle forms. The protein was later called cyclin. Cyclins regulate the timing of the cell cycle.

∙ 13y agoCyclins-a group of protein-regulate the timing of the cell cycle in eukaryotic cells. There are two types of these regulatory proteins: internal regulators and external regulators.

What occurs when the cell cycle is no longer regulated?
The cell cycle goes out of control and cancer develops.
What can happen when the cell cycle is not properly regulated?
Loss of control within the cell cycle is often caused by a disease of the cell cycle known as cancer in which cells lose the ability to control their own growth and tumors can be formed as byproducts of this loss of control as well as injuries to surrounding tissues and muscles.
Why is it important for the Cell cycle to be highly regulated?
Regulation of the cell cycle prevents cell from multiplying and growing when they are not needed. In abnormal cells, they continue through the cell cycle without crucial stop and checkpoints . These checkpoints are important because this is how the cell determines if the phase before was carried out properly. Lots of cancers form because of this. Cell that proliferate through its cycle and continue to grow and grow and grow.
What is the timing of the cell cycle regulated by?
when the cell reaches a certain point then the surface-to-volume ratio can't take in enough energy so it cant grow and it splits
Regular sequence of growth and division that cells undergo?
THE CELL CYCLE.
What occurs when the cell cycle is no longer regulated?
The cell cycle goes out of control and cancer develops.
Occurs when the cell cycle is no longer regulated?
The cell cycle goes out of control and cancer develops.
What are two ways that cell division is regulated in healthy cells?
internal and external factors regulate the cell cycle
What two ways that cell division is regulated in healthy cells?
internal and external factors regulate the cell cycle
How is the cell cycle monitored?
It is regulated by various enzymes and negative feed-back mechanisms.
Is eukaryotic cells the timing of the cell cycle regulated by cyclins?
Yes. Called cyclin dependent kinases.
Is it true that the cell cycle is regulated very tightly?
The cell cycle is regulated by three checkpoints viz G1, G2 and Meta phase checkpoints. Check points help to detect DNA damage and repair it. If repair is not possible then it generate signals to destruct the cell via apoptosis. Hence the statement is true. true
Can cancer result when cells are insensitive to signals that begin the cell cycle?
All cell cycle phases are regulated at cell cycle checkpoints that comprise of receptor collectivities. Defects at the checkpoint of the G1 and G2-M phases lead to cancer by allowing and enhancing the proliferation of cancer cells.
What can happen when the cell cycle is not properly regulated?
Loss of control within the cell cycle is often caused by a disease of the cell cycle known as cancer in which cells lose the ability to control their own growth and tumors can be formed as byproducts of this loss of control as well as injuries to surrounding tissues and muscles.
What is the relationship between cancer and cells?
All cancer is related to the cell cycle. The cell cycle is the cycle of events and regulations that occur through the life of a cell. Part of the cell cycle is cell division. This process needs to be carefully regulated, because un-controlled cell division is called cancer. There are molecules within a cell that respond to signals and stimuli from the envoronment to decide is the cell is allowed to divide. These pathways relay mostly on cyclin and cyclin-dependent kinases. If the regulations fail in a cell - in this case, a skin cell - then you have a cencerous condition in the tissue - in this case, skin cancer.
