title: Distance between alleles as a determinant of linkage in natural transformation of Acinetobacter calcoaceticus.
abstract: Cotransformation frequencies of 16, 39, 51, and 60% were observed when donor alleles were separated by distances of 9.2, 7.4, 6.3, and 5.1 kb, respectively, in donor Acinetobacter calcoaceticus DNA. A different and unexpected pattern was observed when the distance between recipient alleles was reduced from 9.2 to 5.1 kb. Ligation of unlinked chromosomal DNA fragments allowed them to be linked genetically through natural transformation.
