Tandemly Duplicated a Globin Genes of Gibbon
The a globin gene locus of the common gibbon (Hylobates lar) was isolated, and it contains two closely linked a globin genes that share the same arrangement as that found for the homologous genes of other catarrhine primates. The nucleotide sequences of the gibbon a globin genes were determined and compared with the a globin gene sequences from other primate species (human, chimpanzee, oranguta...
متن کاملIntergenic DNA sequences flanking the pseudo alpha globin genes of human and chimpanzee.
We have determined the sequence of 2400 base pairs upstream from the human pseudo alpha globin (psi alpha) gene, and for comparison, 1100 base pairs of DNA within and upstream from the chimpanzee psi alpha gene. The region upstream from the promoter of the psi alpha gene shows no significant homology to the intergenic regions of the adult alpha 2 and alpha 1 globin genes. The chimpanzee gene ha...
متن کاملThe orangutan adult alpha-globin gene locus: duplicated functional genes and a newly detected member of the primate alpha-globin gene family.
We have cloned and sequenced the complete alpha 1- and alpha 2-globin genes of the orangutan, and here we compare them to the homologous genes of the human. The pattern of similarity apparent among the genes is most consistent with a model of gene correction operating on the primate alpha-globin cluster. This correction breaks down in both human and orangutan in the 3'-untranslated region at 14...
متن کاملA limited number of globin genes in human DNA.
The number of globin genes in human cells was determined by hybridizing DNA from human spleens to (3)H-labeled DNA complementary to human globin mRNA. Assuming the rates of reannealing of complementary DNA and cellular DNA are similar, the extent of hybridization of complementary DNA at various ratios of cellular DNA to complementary DNA indicate that there are fewer than 10 globin gene copies ...
متن کاملQuantitation of human gamma globin genes and gamma globin mRNA with purified gamma globin complementary DNA.
Complementary DNA (cDNA) specific for gamma-globin nucleotide sequences has been prepared by hybridizing total cDNA made from cord blood messenger RNA (mRNA) as template to an excess of normal adult human globin mRNA and recovering the single-stranded cDNA from hydroxylapatite. The specificity of the gamma cDNA for gamma mRNA sequences is strongly supported by the hybridization of this cDNA at ...
