Figure 5.
Effect of spermidine on the transformation of B. subtilis BR 151.
Sites 1 and 2: DNA samples of 5 µg ( ) or 0.5 µg of donor DNA per ml ( )
were incubated for 20 minutes prior to the addition of cells. Sites 3 and 4:
Competent cells were incubated for 40 minutes with spermidine prior to the

addition of 5 µg of donor DNA per ml ( ) or 0.5 µg of donor DNA per ml ( ).

The graph in Fig. 6 contains the same data as the graph in Fig. 5. In Fig. 6, the data variables are shown as dashed
lines.

Fig. 7 is the same graph with the x-axis grid shown in light gray so as not to confuse the grid with the important data
indicators. If you wish to include gridlines for clarity, set them 1 point thick on a 15% gray. However, the gridlines in
Fig. 7 give the graph a very cluttered appearance.
