<h2>a) is the correct option </h2>
Explanation:
The extracellular domain of the transmembrane receptor protein acts as binding site for primary messenger molecule whereas the transmembrane domain holds the receptor within membrane and the cytosolic domain has intrinsic tyrosine kinase activity, all these helps in proper cell signaling 
If because of any mutation there is change in shape of the extracellular domain then that molecule that normally binds to the receptor protein will no longer attach hence cellular response will be deactivated 
 
        
        
        
Answer:
The correct answer is They both contain carbon ,but only nucleic acid contain phosphorous
Explanation:
Carbohydrates are also called polyhydroxyaldehydes or polyhydroxyketones.Carbohydrates contain carbon,hydrogen and oxygen.For example glucose(C6H12O6).
    On the other hand nucleic are composed of nucleotides that contain nitrogen base,ribose sugar and phosphate group.
      The presence of phosphate group in the nucleic acid make it different from carbohydrate.
