A DNA mutation changes the shape of the extracellular domain of transmembrane receptor protein A produced by the cell. Which of the following predictions is the most likely consequence of the mutation? (Figure)

a. The molecule that normally binds to protein AA will no longer attach, deactivating the cellular response.
b. The glucocorticoid receptor will remain associated with the accessory proteins.
c. The intracellular concentration of glycogen will increase.
d. The SRYSRY gene produces a protein that binds to specific regions of DNADNA in certain tissues, which affects the development of these tissues.
