摘要: Abstract The genomic organization of the mouse dihydrofolate reductase gene has been determined by hybridization specific cDNA sequences to restriction endonuclease-generated fragments DNA from methotrexate-resistant S-180 cells. contains a minimum five intervening (one in 5′ untranslated region and four protein-coding region) spans 42 kilobase pairs on genome. Genomic at junction sequence mRNA-coding polyadenylation site have determined. A similar is found independently isolated cell lines, parental sensitive line several inbred strains, indicating that this represents natural gene.
