title: The restriction endonuclease Alu I induces chromosomal aberrations and mutations in the hypoxanthine phosphoribosyltransferase locus, but not in the Na+/K+ ATPase locus in V79 hamster cells.
abstract: The restriction endonuclease Alu I induces chromosomal aberrations and mutations in the hypoxanthine phosphoribosyltransferase (HPRT) locus as measured by 6-thioguanine resistance (TGr) in V79 hamster cells. Alu I does not induce mutations in the Na+/K+ ATPase locus as measured by ouabain resistance (OUAr). The data are interpreted to mean that most if not all Alu I-induced TGr mutations represent chromosomal aberrations.
