- Description:
- Caption by Maclyn McCarty reads: "An example of the experiments making use of purified DNase to show that transforming DNA was not 'taken up' by the growing rough pneumococci until 3 to 4 hours after inoculation. This was the first indication that the state of 'competence' took time to develop. Competence developed only during growth in the complete culture medium used for transformation."
