title: Enumeration and identification of IS3 elements in Escherichia coli strains.
abstract: Escherichia coli K-12 strains ordinarily contain five IS3 elements. Three of these correspond to previously mapped IS3 elements (R. C. Deonier, G. R. Oh, and M. Hu, J. Bacteriol. 129:1129--1140, 1977; S. Hu, E. Ohtsubo, and N. Davidson, J. Bacteriol. 122:749--763, 1975), and two additional IS3 elements are identified. The distribution of IS3 elements among deoxyribonucleic acid fragments generated by digestion with EcoRI indicates a basic pattern from which deviation is detected.
