摘要: A population of Bacillus subtilis can be fractionated into at least two components on the basis their buoyant densities a Renografin gradient. In competent cultures, most, and perhaps all, bacteria appear in lighter fraction which composes 2 to 10% bulk population. These “lighter” are only capable incorporating transforming deoxyribonucleic acid. Images
