Question

You are a mad scientist that created a transgenic mouse line with a mutation in a protein that you call the Hulk protein. Hulk mutations lead to really muscular mice due to an overgrowth of muscles via uncontrolled muscle cell proliferation (growth). Which of the following types of mutation would be expected to produce this phenotype? a mutation that inactivates the protein tyrosine phosphatase that normally removes the phosphates from tyrosines on the activated receptor a mutation that prevents the binding of the normal extracellular signal to an RTK a mutation that prevents dimerization of an RTK O a mutation that destroys the kinase activity of an RTK

Answer 1

Answer- The correct option is A that is the mutation that inactivate the protein tyrosine phosphatase that normally removes the phosphate from tyrosine in the activated receptors. Because it's mutation will lead to uncontrolled growth of the cells.
