FIG 8.

Relationship between genome and virion sizes for 13 viruses excluded from the original analysis because only a range of virion volumes were available (Table 3). RNA viruses are shown by open circles and DNA viruses by closed circles. The solid black line marks the prediction line calculated for our original analysis (Fig. 1). The outer gray lines represent the 95% prediction interval for our original analysis, within which we expect 95% of predicted virion sizes to lie.
