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.

1
T1: live, T2: die, T3: live, T4: die, TS: die, T6: live 
2
T1: live, T2: live, T3: die, T4: live, T5: live, T6: live
3
T1: live, T2: die, T3: die, T4: die, T5: live, T6: die 
4
T1: live, T2: die, T3: die, T4: live, T5: die, T6: live
