Question

a mutation is an abnormal change in the DNA within a cell, sometimes resulting in an accelerated pattern of somatic cell division. The acceleration is often caused by an interphase that is much more brief than normal. If left unchecked, a mutation of this sort can result in tumor formation and cancer. Suggest a method of stopping this type of unregulated cell division

Answer 1

Answer. The unregulated cell division can be stopped by the checkpoint at every phase of the cell cycle. These checkpoint checks and validate the process in that phase of cell cycle is completed or not if not then it will halt the cell cycle and cell will not enters into M-phase. There are several checkpoint like G1 checkpoint, G2 checkpoint and Metaphase checkpoint. The protein and enzyme plays role are known as cyclin or cdks. So these are the steps through which a cell division is stopped. If there is any mutation or alteration in these process then it will halt on to next or it will leads to apoptosis of cell.
