To MOST readily demonstrate transformation of bacteria in the laboratory one could extract DNA from:

Question

Quizplus · Accepted Answer

arg⁺ cells and add it to arg^- cells.Transformation is the process of introducing foreign DNA into a cell. In this case, we want to demonstrate transformation of bacteria, so we need to introduce DNA from one strain of bacteria into another strain. The DNA from the donor strain should contain a gene that is not present in the recipient strain. In this case, we have arg⁺ cells (which have the arg gene) and arg^- cells (which do not have the arg gene). If we extract DNA from the arg⁺ cells and add it to the arg^- cells, the arg^- cells will be able to take up the DNA and incorporate it into their own genome. This will allow the arg^- cells to produce the Arg protein, which they were not able to do before. This will demonstrate transformation of bacteria.
