Essentially, cancer is a condition caused by unchecked cell division. Its growth and development are typically correlated with a number of modifications in the activity of cell cycle regulators.
What condition causes cells to cycle through the cell cycle uncontrollably?
Cells that divide uncontrolled and invade neighboring tissues are what cause cancer. DNA alterations are the root cause of cancer. Most DNA alterations that cause cancer take place in regions of DNA known as genes. Genetic alterations are another name for these modifications.
This process is tightly regulated to guarantee that the DNA of a dividing cell is accurately duplicated, that any DNA errors are corrected, and that each daughter cell obtains a complete set of chromosomes. Checkpoints, also known as restriction points, are locations in the cell cycle when specific genes can check for issues and stop the cycle for repairs if something is wrong.
