A method has been described for the isolation of DNA from micro-organisms which yields
stable, biologically active, highly polymerized preparations relatively free from protein and
RNA. Alternative methods of cell disruption and DNA isolation have been described and
compared. DNA capable of transforming homologous strains has been used to test various
steps in the procedure and preparations have been obtained possessing high specific ...
