title: Transforming ability of bacterial deoxyribonucleic acid in relation to the marker efficiencies in Diplococcus pneumoniae during thymidine starvation.
abstract: Thymidine starvation induces a decrease in transforming activity of pneumococcus deoxyribonucleic acid. The integration of low- and high-efficiency markers seems to be equally affected.
