BIOXII06: MOLECULAR BASIS OF INHERITANCE
343209
The result of the following reaction/experiment carried out by Avery et al., on Streptococcus pneumoniae has proved conclusively that DNA is the genetic material:
1 Live 'R' strain + DNA from ' S ' strain + DNAase
2 Heat killed 'R' strain + DNA from ' S ' strain+ DNAase
3 Live ' 'R' ' strain +DNA from ' S ' strain + RNAase
4 Live ' 'R' ' strain + Denatured DNA of ' S ' strain + protease
Explanation:
The group of mice injected with a mixture of live \(\mathrm{R}\) strain and heat-killed \(\mathrm{S}\) strain of pneumococci, neither of which is lethal by itself. Some of the mice which received the mixture also died of pneumonia. The live \(\mathrm{S}\) strain as well as \(\mathrm{R}\) strain bacteria were recovered from the dead mice. It was found that only DNA was responsible for transformation because when DNA was treated with DNase (which degraded DNA), transformation was not possible.

Statement A : The uptake of DNA during transformation is an active, energy requiring process. Statement B : Transformation occurs in only those bacteria, which possess the enzymatic machinery involved in the active uptake and recombination.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Transformation does not affect the passive entry of DNA molecules with the help of permeable cell walls and membranes. It does'nt occur naturally in all bacteria species and only occur in those species who acquire the enzymatic machinery engaged in direct uptake and recombination procedures. Thus, the commencement of transformation, the recipient bacteria must be in competence state.
