Right option is (a) True
The explanation: The efficiency of this rapid technique depends on the Concentration of DNA in a solution, the timing of the addition of DNA, size and condition of the beads and the buffers utilized. In this method, the adherent cells are incubated for a brief period with glass beads in a solution containing the DNA. Then the m=solution is mixed such that the beads collide and the cells coming in between the beads may get pores.
