Fate of Transforming Deoxyribonucleic Acid After Uptake by Competent Bacillus subtilis: Size and Distribution of the Integrated Donor Segments

D Dubnau 1, C Cirigliano 1
PMCID: PMC251309  PMID: 4626501

Abstract

A series of sheared donor-recipient complex samples were prepared from a competent Bacillus subtilis culture which had been transformed by using 3H, 2H-labeled deoxyribonucleic acid. Measurement of the molecular weights and buoyant densities of these samples led to the following conclusions. (i) The average size of the single-stranded donor segment which is integrated is 2.8 × 106. (ii) These donor segments are not randomly distributed in the recipient genome, but are clustered in groups, each group containing several discrete donor segments.
