METHICILLIN-INDUCED LYSOZYME-SENSITIVE FORMS OF STAPHYLOCOCCI.

abstract：:A segment of Escherichia coli DNA that contained a discontinuity of homology with Salmonella typhimurium DNA was isolated. The segment, 1,430 base pairs long, was derived from one end of the lac "loop," a region of about 12 kilobase pairs of E. coli DNA, including the lac operon which has no detectable homology with S...
