A mutation in the gene for hormone A causes it to be unable to bind to its receptor protein. What do you predict will likely happen?
A) The receptor protein will not be activated and therefore will not initiate a signal transduction pathway.
B) The receptor protein will change shape in order to bind with hormone A.
C) The hormone will bind with a different receptor instead.
