Number of transformable units per cell in Diplococcus pneumoniae.

Abstract

Analysis of frequencies of single and random multiple transformations in Diplococcus pneumoniae showed that there are at least two transformable units per cell of the total population in highly competent cultures. If 100% of the cells are competent in these cases, the units may be interpreted as the strands of one duplex deoxyribonucleic acid recipient chromosome. The theory is developed to allow for extension to more complex situations.
