a- Pick out the involved protein & the abnormal phenotype due to its absence.
b- Formulate two hypotheses at the origin of this abnormality.
c- We inject the albino person by tyrosine
i- If the albino recovered his pigment then the problem was in:..
ii- If the albino couldn't recover his pigment then the problem was in:..
2. Cellular Proteins
Muscle cells produce dystrophine protein interferes in the structural constitution of mue
fibers.
Absence of dystrophine protein →Weak muscle fibers → atrophy of muscles →leading to musela
paralysis, It is called:
Duchene Muscular Dystrophy (DMD) (Myopathy):
d- Pick out the involved protein & the abnormal phenotype resulted from it.
e- Formulate a hypothesis at the origin of this abnormality.
Normal RBC → Produces hemoglobin protein HBA → binds &transports respiratory gases.
Affected RBC → Produces hemoglobin HBS → Can't binds & transports respiratory gases.
HBS differs in 1 amino acid from HBA. It becomes insoluble and
accumulates (precipitates) in the cytoplasm of RBC's leading to
their distortion (deformation) & hence their destruction.
This case is diagnosed as: Sickle cell anemia.

f- Pick out the abnormal protein & the abnormal phenotype resulted from it.
g- Formulate a hypothesis at the origin of this abnormality.
