Question
A mutation in the human gene BIOL increases the activity of the protein produced by expression of the BIOL gene. This mutation has been found in many different types of cancer. Based only on this information, which of the following is a reasonable prediction?
1. The protein produced by expression of the BIOL gene inhibits cell division. 2. The protein produced by expression of the BIOL gene promotes cell division. 3. The protein produced by expression of the BIOL gene either promotes or inhibits cell division. 4. The protein produced by expression of the BIOL is not important for either promoting or inhibiting cell division.Explanation / Answer
Cancer is characterized by uncontrolled growth of cell that keeps on proliferating and sometimes travels drifted to other site through bloodstream. Every cell undergoes cellular metabolic pathways to generate energy molecules. Generally, adenosine triphosphate (ATP) molecules are produced by three major pathways namely glycolysis, citric acid cycle, and electron transport chain.
The four major causes of cancer are as follows:
Thus, based on the above information, the mutation in BIOL gene has increased the formation of protein, which may be involved in uncontrolled cell division.
Hence, the correct option among the following is 2.
