A Physician Is Trying to Block the Expression of a Gene

A physician is trying to block the expression of a gene that causes a protein in the cell membrane to be abnormally shaped.What would be the easiest way to block the expression of the gene if it is due to the presence of a steroid protein?

A) The physician should alter the composition of the plasma membrane making it impermeable to the steroid hormone or alter the composition of the steroid hormone making it insoluble in lipids.
B) The physician should find a way to alter the shape of the receptor molecules inside the nucleus.This would prevent the hormone form binding.
C) The physician should develop a drug that would block transcription from occurring.If this is done,then the code for the gene would not be formed.
D) The physician should develop a method to prevent the ribosome from translating the mRNA code into the particular protein.
E) The physician should develop a vaccination that would denature the protein once it has been formed.This would prevent the protein from being able to express its particular trait.
