RESUMO
Density gradient centrifugation was used to monitor DNA replication during sporulation of a 5-bromo-2'-deoxyuridine-tolerant, thymidine-requiring strain of Bacillus subtilis. DNA of heavy, intermediate, and light density was found in cells induced to sporulate in the presence of bromodeoxyuridine, but only intermediate DNA was detected in mature spores. Cells grown with bromodeoxyuridine until DNA was in the heavy form formed spores containing intermediate and light DNA when sporulated with thymidine alone.
