NATURE文献大全abstract::The alpha-like and beta-like globin genes have provided a paradigm for the study of molecular evolution and regulation of multigene families in eukaryotes. The human alpha-globin gene cluster, which is on chromosome 16 (ref. 1), consists of six genes arranged in the order 5'-zeta(embryonic)-psi zeta-psi alpha 2-psi al...

abstract::The ability to excise (repair) UV-induced pyrimidine dimers in Escherichia coli is not related to its ability to remove N-methyl-N'-nitro-N-nitrosoguanidine (MNNG)-induced O6-methylguanine (O6-MeG) from DNA. It was therefore surprising that certain xeroderma pigmentosum cell lines, deficient in dimer excision, were al...
