Motivated by the classic experiment by Frederick Griffith and the work of Avery, Macleod and McCarty to identify the transforming principle, a scientist redesigned and performed the experiment with S-strain and R-strain of Streptococcus pneumoniae as summarized in the table below.
|
Treatment |
Experimental Condition |
|
T1 |
S-strain (heat-killed) injected into mice |
|
T2 |
S-strain (heat-killed) + R-strain (live) together injected into mice |
|
T3 |
Nucleic acids isolated from S-strain (heat-killed) + R-strain (live), incubated with RNase, and injected into mice |
|
T4 |
Nucleic acids isolated from S-strain (heat-killed) + R-strain (live), incubated with DNase, and injected into mice |
|
T5 |
S-strain (live) injected into mice |
|
Ꭲ6 |
R-strain (live) injected into mice |
From the options below, identify the outcomes of the treatments (T1 to T6) on the viability of the mice.
