Question

describe a scenario during the interphase portion of the cell cycle that can lead to cancer

Answer 1

Interphase is the stage in which the cell is not dividing, normally cancer can occur in this stage if enough DNA daamage is accumulated, if cell cycle genes get damaged then the cell will not follow the cycle anymore and will turn into a cancer cell. A proper scenario for this could be the exposure to high energetic levels of light radiation, this radiation causes dimerization in the bases, which in turn cause complication during replication, that is because these dimers cannot be correctly read by polymerase, they cannot be replicated. The cell cannot complete the S phase, and cannot enter the M phase, the cell cycle is disrupted and the cell might cause cancer if it is not eliminated.
