Total human DNA was cleaved with a variety of restriction enzymes, and the fragments were fractionated by gel electrophoresis and transferred to nitrocellulose filter strips. The restricted DNA was then hybridized to nick-translated radioactive recombinant plasmid DNA containing sequences derived from human beta-globin messenger RNA. Under suitable conditions, this probe hybridizes with both the beta--and delta-globin genes. Using this probe, a restriction map of the human beta--and delta-globin genes and the surrounding genomic DNA regions has been constructed. The beta-globin gene contains a nonglobin DNA insert approximately 899-1000 base pairs in length, present within the sequence coding for amino acids 101-120 of the 146 amino acid long globin polypeptide. A similar sequence may be present within the same sequence of the delta-globin gene. The distance between the beta--and delta-globin genes is approximately 7000 nucleotide pairs, and the delta-globin gene is to the 5' side of the beta-globin gene, as predicted by genetic evidence. Both genes are transcribed from the same DNA strand. The structure of the Hb Lepore gene is shown to be a fused delta--and beta-globin gene, and to be completely consistent with the derived map of normal beta--and delta-globin genes. [Restriction enzyme nomenclature follows that of Smith and Nathans (1973) and Roberts (1976). A genomic DNA restriction fragment containing part or all of one globin gene will be designated by that globin chain--for instance, the Pst I fragment containing the beta-globin gene sequence will be designated Pst I beta. A similar convention will be used for double digests. Throughout this paper, when reference is made to the 5' or 3' side or fragment of a gene, this refers to the 5' or 3' side of the mRNA coded by that sequence. Thus the 5' side (N terminal) of the beta-globulin gene is the sequence to the 5' side of the anti-sense strand.].
