PLEASE EXPLAIN YOUR ANSWER!
To demonstrate transformation of bacteria, one could:
extract DNA from StrS cells and add it to StrR cells.
extract DNA from an auxotroph and add it to prototrophic cells.
extract DNA from arg- cells and add it to arg+ cells.
mix the DNA from arg+ and arg- cells to allow recombination.
extract DNA from arg+ cells and add it to arg- cells.
A.extract DNA from StrS cells and add it to StrR cells.
B.extract DNA from an auxotroph and add it to prototrophic cells.
C.extract DNA from arg- cells and add it to arg+ cells.
D.mix the DNA from arg+ and arg- cells to allow recombination.
E.extract DNA from arg+ cells and add it to arg- cells.
Explanation / Answer
Answer is: extract DNA from arg+ cells and add it to arg- cells.
Transformation is one of three processes for horizontal gene transfer, in which exogenous genetic material passes from one bacterium to another. The DNA is transfer from arg+ cells to arg- cells because arg- lacking the supplement for the growth and without supplements the cell lacking arg will die.therefore the genetic material transfer from arg+ and add it to arg- cells.
