title: Detection of different types of receptors for deoxyribonucleic acid in competent Bacillus subtilis.
abstract: Competent cells of Bacillus subtilis are able to bind but not to take up DNA in magnesium-free medium. Wall-membrane complexes, but not cell walls, bind homologous DNA. Binding of DNA  to membrane vesicles suggests that DNA-receptor sites are located at the membrane level. On the basis of competition experiments with homologous and heterologous DNAs, in cells and in membrane vesicles, different types of DNA receptors are detected.
