What is one of the greatest challenges that a patient will face while they are receiving treatments to kill cancer cells? 5. Considering the differences between a benign tumor and a malignant tumor, why might a benign tumor be easier to treat than a malignant tumor? 337

Explanation / Answer

1. The cell cycle is controls the growth of cells in the body. If an pay of the cells are mutated, these lead to the development of uncontrolled and unregulated cell growth. This unregulated cell growth occurs as a result of mutation in the oncogene D1 with an increase in the cyclin dependent kinases.

2. The cell cycle is controlled by the action the action of cyclins, the retinoblastoma protein, and the transcription factor E2F. E2F binds along with the pRB to facilitate its binding to the DNA, leading to trasncription of the protein under the influence of cyclin dependent kinases. Once the cell cycle is complete, CDK4s comes into action to inhibit cell growth and cause senescence.
