Glucose transporter of erythrocytes (GLUT1) is an integralmembrane protein responsible for supplying red blood cells withglucose from blood plasma.

a) Would you expect to find hydrophobic or hydrophilic aminoacids in the interior of this protein (where the glucose binds)?Explain in terms of the structure of glucose and intermolecularforces and give two specific examples of this type of aminoacid.

b) Would you expect to find hydrophobic or hydrophilic aminoacids on the exterior of the glucose transporter protein (the partinteracting with the interior of the membrane)? Explain in terms ofthe structure of cell membranes and intermolecular forces and givetwo specific examples of this type of amino acid.

Assume that cancer results from a point mutation in DNA, whichchanges the second nucleotide of the codon CGG. This results in achange of an amino acid (or an amino acid substitution) in a keysmall protein. In this experiment you will find out what themutation is and address its consequences.

The following mRNA was translated from a person with cancer.Find the same base mutation in the following sequence from a cancercell. (Hint: Find the start and stop codons and translate the mRNAinto protein). Show your work.
