A Physician Is Trying to Block the Expression of a Gene

question 44

Multiple Choice

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.
