Abstract

DNA isolated from exponentially growing cultures of Bacillus cereus T has a single component (density 1.696 g cm-3) in a cesium chloride density gradient whereas DNA isolated from spores shortly after the initiation of germination has two components: a major one (density 1.696 g cm-3) and a satellite (density, 1.725 g cm-3). The DNA of both components is doublestranded. By the first cell division there is no satellite DNA.
