The restriction point occurs during what phase of the cell cycle?
G1
What is the restriction point in mammalian cells?
In the mammalian cell cycle, a time late in the G1 phase at which the cell commits to the replication of its deoxyribonucleic acid (DNA).
What is cancer what causes it and how is it related to the cell cycle.?
Cancer is a disease of cells causing uncontrolled cell division. Certain proteins are a control system that regulate passage through a restriction point. This means that once the cell division cycle begins it will continue to the end.Altered regulation of expression of at least one protein (cyclin) as well as mutations of several proteins that regulate passage through the restriction point can be cancer producing.
What is a cycle of an abnormal cell?
Cancerous cells go through the same cycle as every other cell, except for that there are no checkpoints for the duplicating DNA and such to be proofread in, and usually they don't wait for the restriction signal to tell it to duplicate, it just does uncontrollably.

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 is the best explanation for why a restriction enzyme does not cut the DNA of the cell that produces it?
The cell's DNA does not contain the restriction site.
At what point in the reproductive cycle of the T4 bacteriophage is host cell infection irreversible?
Once the viral DNA is duplicated in the cell.
When does a cell make sure its DNA has been copied correctly before continuing in the cell cycle?
G2 check point.
What point in the reproductive cycle of the T4 bacteriophage is host cell infection irreversible?
Once the viral DNA is duplicated in the cell.
Mitotic cell division is initiated in the?
CDC7 is involved in regulation of the cell cycle at the point of chromosomal DNA replication。
Regular sequence of growth and division that cells undergo?
THE CELL CYCLE.
