To demonstrate transformation of bacteria,one could: A)extract DNA from an auxotroph and add it to prototrophic cells. B)extract DNA from arg^- cells and add it to arg⁺ cells. C)extract DNA from arg⁺ cells and add it to arg^- cells. D)extract DNA from Str^S cells and add it to Str^R cells. E)mix the DNA from arg⁺ and arg^-cells to allow recombination.

Question

Quizplus · Accepted Answer

Transformation in bacteria involves taking up external DNA and incorporating it into their genome. In choice C, DNA from a cell with a positive trait (arg⁺) is added to a cell lacking that trait (arg^-), which could result in the transformation of the recipient cell if the DNA is incorporated, thereby demonstrating transformation.
