How does a cell know when to carry out mitosis and when not to carry out mitosis?
Cells regulate the cell cycle through checkpoints that monitor cell conditions. Factors such as DNA damage, cell size, and growth signals determine whether a cell should proceed with mitosis or pause the cell cycle to repair damage. If conditions are not favorable, the cell will not enter mitosis.
What kinds of factors regulate a cells progress through the cell cycle?
There are no regulating factors. Mitosis itself is a process that takes time. The cells must go through various stages before they even enter their mitotic phase of the cycle. Once in the mitotic phase, even more phases before mitosis is complete. It would take me hours to thoroughly get into each of the stages of mitosis.
What are places in a cell cycle that control whether the cell will divide?
Key checkpoints in the cell cycle that control whether the cell will divide include the G1/S checkpoint, which assesses DNA damage and cell size before entering DNA synthesis phase, and the G2/M checkpoint, which checks for DNA replication and repairs before entering mitosis. Additionally, the cell relies on checkpoints during metaphase to ensure proper attachment of chromosomes to the mitotic spindle.
The mechanisms that regulate when a cell divides fail to work in cancer patients true or false?
True. In cancer patients, the mechanisms that regulate cell division, such as checkpoints and tumor suppressor genes, often fail to function properly. This can lead to uncontrolled cell growth and division, a key characteristic of cancer.
Why pea root cells and salamander kidney cell takes the same for mitosis?
Pea root cells and salamander kidney cells take the same amount of time for mitosis because they both undergo similar stages of cell division, including prophase, metaphase, anaphase, and telophase. The duration of mitosis is typically consistent across different cell types in a species due to the regulated control of cell cycle checkpoints and the coordination of cellular machinery involved in mitosis.
Before a cell can proceed to mitosis from the gap 2 stage of the cell cycle it must?
Undergo a series of checkpoints, including checking for DNA damage and ensuring that the cell has replicated its DNA correctly. If the checkpoints are passed, the cell will proceed to mitosis. If issues are detected, the cell may pause for repair or undergo programmed cell death.
What would happen if there were no spindle checkpoints?
If there were no spindle checkpoints then the chromosomes wouldn't be in the right position for the reproduction of the cell.
How does a cell know when to carry out mitosis and when not to carry out mitosis?
Cells regulate the cell cycle through checkpoints that monitor cell conditions. Factors such as DNA damage, cell size, and growth signals determine whether a cell should proceed with mitosis or pause the cell cycle to repair damage. If conditions are not favorable, the cell will not enter mitosis.
What part of the cell controls the process of mitosis?
The cell cycle is regulated by a group of proteins called cyclins and cyclin-dependent kinases (CDKs). These proteins work together to control the progression of a cell through the stages of the cell cycle, including mitosis. Regulatory checkpoints also help ensure that the process of mitosis is properly regulated.

What give the signal for a cell to divide in the Cell Cycle?
Various signals, such as growth factors, nutrient availability, and DNA damage, can trigger a cell to divide in the Cell Cycle. These signals activate specific checkpoints and regulatory proteins within the cell to ensure that conditions are favorable for cell division to proceed.
During which stage is DNA replication evaluated to see if the cell is ready to move on with mitosis?
The cell cycle is controlled by three internal checkpoints that evaluate the cell to the next stage in the cycle can be halted until conditions are favorable.
What are the 5 control factors for mitosis?
The five control factors for mitosis are cyclin-dependent kinases (CDKs), cyclins, checkpoints, growth factors, and tumor suppressor genes. These factors help regulate the progression of the cell cycle and ensure that mitosis occurs correctly.
What are places in a cell cycle that control whether the cell will divide?
Key checkpoints in the cell cycle that control whether the cell will divide include the G1/S checkpoint, which assesses DNA damage and cell size before entering DNA synthesis phase, and the G2/M checkpoint, which checks for DNA replication and repairs before entering mitosis.

When does a cell move into the mitosis checkpoint?
well the mitosis checkpoint is right before anaphase, meaning at the end of metaphase right befoer it is about to split. So i suppose whenever it enters metaphase then it will undergo the checkpoint. This checkpoint is extremely importnant for the cell and makes sure there are no mistakes before the cell reproduces.
