Paper Details
In the experiment of Figure 7.1, Joshua Lederberg and Edward Tatum could not discern whether met+ bio+ genetic material was transferred to the met- bio- thr+ leu+ thi+ strain or if thr+ leu+ thi+ genetic material was transferred to the met+ bio+ thr- leu- thi- strain. Let's suppose that one strain is streptomycin-resistant (say, met+ bio+ thr- leu- thi-) and the other strain is sensitive to streptomycin. Describe an experiment that could determine whether the met+ bio+ genetic material was transferred to the met- bio- thr+ leu+ thi+ strain or if the thr+ leu+ thi+ genetic material was transferred to the met+ bio+ thr- leu- thi- strain.
