RESUMO
Two distinct alpha-globin mRNAs were detected in chimpanzee reticulocyte mRNA using a primer extension assay. DNA copies of these two mRNAs were cloned in the bacterial plasmid pBR322, and their sequence was determined. The two alpha-globin mRNAs have obvious structural homology to the two human alpha-globin mRNAs, alpha 1 and alpha 2. Comparison of the two chimpanzee alpha-globin mRNAs to each other and to their corresponding human counterparts revealed evidence of a recent gene conversion in the human alpha-globin complex and a marked heterogeneity in the rate of structural divergence within the alpha-globin gene.
