A relаtively smаll number оf genes аppear tо accоunt for much of the variation in skin color observed in humans. Two genes that have undergone positive selection in northern latitudes are OCA2 in Asian populations and SLC24A5 in European populations. In the ancestral African population, the SLC24A5 gene produces a protein with an alanine at amino acid position 111. In the European population the amino acid at position 111 is threonine. The protein that is produced from the SLC24A5 gene exchanges an ion of Na+ from the cell cytoplasm for a Ca2+ ion on the outside of the cell. This exchange appears to be necessary for normal melanin synthesis. In East Asian populations, the OCA2 gene produces a protein with the amino acid arginine at position 618 whereas the ancestral amino acid at that position is histidine. For both genes, the mutation arises from a single base change called a Single Nucleotide Polymorphism. The anticodon on the tRNA for alanine is CGU and the anticodon for threonine is UGU. What is the DNA base change that resulted in the SLC245A mutation?
