Predicted terminator propensities in operons. Propensity of over-represented intra-operonic genes (OIGs) and non-over-represented intra-operonic genes (NOIGs) predicted to have a terminator in their upstream intergenic region for all GDSL threshold bins compared to random. Propensities were calculated by dividing the fraction of OIGs or NOIGs with a predicted terminator by the fraction of all genes that were OIGs or NOIGs in this restricted 78 gene subset. This was done for non-inclusive 10 base-pair regions moving out from the stop codon of the previous gene. Random values were estimated by random picking from the 78 gene intra-operonic set to represent the OIG and NOIG expressed data sets, repeating 1,000 times.
