Figure 4

Specific mutations found in Qβ phage selected on W and 6fW. Of the upper portion of the figure, the first column indicates the protein affected by mutations, the second column indicates the specific genetic mutation and the third column indicates the expected protein mutation. Later columns represent specific populations or clones as indicated. Mutations indicated in the second and third columns are present in the phage in question if a particular cell is filled with the color corresponding to the specific protein in question, as indicated in the first column. The lower portion of the figure presents a summary of the mutations found.
