Mutation Review

The quaternary structure of hemoglobin can be described as:

• four protein chains around a heme group

• globular

• two alpha and two beta protein chains

• all of the above

The disease caused by the lack of beta chain production leading to an excess of iron in the blood is called:

• beta thalassemia 

•  sickle cell anemia

• Gaucher Disease

• none of the above

A mutation that changes the third position in a CUU codon to a C would:

• profoundly change the protein's conformation

• result in a frameshift mutation

• shorten the protein.

• have no effect on the protein.
