Hey there,
Your question states:Hemophilia is a disease that causes uncontrollable bleeding. If a father has it, all of his daughters will be carriers of the disease, and about half of his sons will have the disease. An error in which macro-molecule is the cause of hemophilia?
Based on my calculations ,your correct answer would be [tex]\boxed{nuclear \ acid}[/tex] basically because hemophilia is a disease, and like the statement says above, if the fathers has it then the daughter's would also. The Nuclear acid would be the answer because the acid originates with the DNA, which means that if that is the case, this the fathers offspring would really have this problem.
