Part II: Biochemistry

• What are the differences in the amino acid sequences of the proteins produced by the alleles you define in Part I? Hint: use the Compare menu to find the difference(s)

between the amino acid sequences. Allele Protein Structures

• Green:Met-Ser-Asn-Arg-His-Ile-Leu-Leu-Val-Tyr-Trp-Arg-Gln
• Blue:Met-Ser-Asn-Arg-His-Ile-Leu-Leu-Val-Tyr-Cys-Arg-Gln
• Yellow:Met-Ser-Asn-Arg-His-Ile-Leu-Leu-Val-Trp-Cys-Arg-Gln
• Red:Met-Ser-Asn-Arg-His-Ile-Leu-Leu-Val-Phe-Cys-Arg-Gln
• White:Met-Ser-Asn-Arg-His-Ile-Leu-Leu-Val-Val-Cys-Arg-Gln
• What features of the amino acid sequence make a protein pigmented?
• What features of the amino acid sequence make a protein a particular color?
• How do the colors combine to produce an overall color? How does this explain the

genotype-phenotype rules you found in part (I)?

• Which proteins are found in each of the four starting organisms?
• Using this knowledge, construct a purple protein.
