Figure 4

Relationship between the interval between flanking ORFs ('maximum' length) and transcript length. Measured transcript length in nucleotides (nts) for all nonoverlapping genes is plotted against the inter-ORF interval for each gene. Red squares indicate those transcripts whose length exceeds their theoretical maximum within the precision of the measurement. The identity line is shown in black for clarity. Parentheses indicate how many spots of each type are plotted.
