Exercise 1: Albinism is a hereditary deficiency characterized by the absence of pigmentation in the skin, eyes, and hair, due to the absence of a black pigment: the melanin. Tyrosinase is an enzyme implicated in the biosynthesis of this pigment. The gene coding for tyrosinase exists in different alleles. We consider only 2 alleles: allele A coding for the active tyrosinase responsible for the synthesis of melanin, and allele B coding for the inactive tyrosinase which doesn't allow the synthesis of Albinism melanin. The document below represents a partial sequence of a strand of the 2 alleles A and B. Number 80 81 82 83 84 85 of triplet Allele A TGC САА CGA ТСС ТАТ СТТ ... Allele B TGC САА САА TCC ТАТ СТТ ...

1. A variety of organic chelating ligands have been synthesized to tightly coordinate radioactive metal cations to identify and treat malig- nancies by coupling the metal complex to a polypeptide linker attached to a monoclonal antibody that binds specifically to a cell surface re- ceptor. One such metal complex is illustrated in the diagram on the right. The radioactive Cu-64 cation is tightly coordinated by the che- lating ligand that is, in turn, conjugated to a peptide linker attached to a monoclonal antibody. (The antibody is not shown in this diagram.) When coupled to a specifically designed monoclonal antibody, the complex binds specifically to somatostatin receptors that are ex- pressed on the surface of neuroendocrine tumors. Subsequently the entire complex with the receptor is internalized, i.e., passed into the cytoplasm, where the radioactive metal cation kills the malignant cell.
