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 check point in cell cycle?
The checkpoints in the cell cycle are points were the cell is tested for mutations. There are three checkpoints: one at the G1 stage, at the S stage, and finally at the G2 phase.
What are the three checkpoints where the cell divides?
The three checkpoints are...G1 (restriction) checkpoint: where the decision is made whether the cell will be divided, delayed division or enter the resting stageG2 checkpoint: which checks the success of DNA replication from the S phaseM checkpoint: the process of mitosis is assessed (whether it was a success)If at any time the cell doesn't pass the checkpoints, the cells stops and repairs so that it can continue along the cell cycle.
What is the Name of cell produced through mitosis?
The original cell is the parent cell and the cell split through mitosis is the daughter cell.
In cell cycle where mitosis occurs?
Mitosis (cell division) is complete at the end of the telophase.
What give the signal for a cell to divide in the Cell Cycle?
Well its more of the signals that say "dont go through mitosis" that prevents it from going through mitosis until conditions are right. this is mainly the fact that cells are so tightly squeezed together that they cannot go through mitosis until the one next to it dies or goes through apoptisis (programmed cell death). when a cell dies chemicals are released and sent to the surrounding cells to tell them to start dividing. otherwise a cell should continue dividing. though this doesnt mean cells are constantly dividing because in interphase there are various checkpoints of the cell division that tell the cell its ok to continue dividing. these checkpoints are G1, S, and G2. if the cell doesnt pass these checkpoints it goes into the G0 phase and does not divide.
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 directs the sequential events of the cell cycle?
the sequence of the cell cycle: interphase mitosis prophase metaphase anaphase telophase, describe and defined .

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.
How many cells do we get at the end of mitosis?
Humans have trillions of cells before, during, and after mitosis. It's impossible to determine an accurate number, because cells are constantly dying off and dividing. The number is always changing.
What s the state of a cell about to start mitosis?
The cell cycle has four main parts. Growth 1, Synthesis, Growth 2, and Mitosis. If a cell is about to start mitosis, that means it has passed through the first 2 stages and is in Growth 2. Each stage has checkpoints to make sure the previous stage is completed, so all those conditions like proper nutrients, appropriate division signal, completed DNA synthesis, and large enough size are met when the cell is about to enter mitosis.
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.
What are places in the cell cycle that control whether the cell will divide?
checkpoints
