Candidate Regulatory Sequence Elements for Cell Cycle-Dependent Transcription in Saccharomyces cerevisiae

The number of upstream regions in each of the five sets of cell cycle-regulated genes containing one or more copies of a hexamer was counted. The counts are indicated in the column labeled “No.” The contribution to the χ² score made by each of the data sets is shown, along with the total value of the χ² score. The data set(s) that make the greatest contribution to χ² are indicated in boldface type.P values for each χ² score were calculated from a Monte Carlo simulation. The final column shows the number of upstream regions of the non-cell cycle-regulated genes containing one or more copies of each hexamer. These counts are shown for illustrative purposes only; the numbers were not included in the χ²calculation.
