- Table 4 described the first column shows the name of the pathway. The second column lists the number and percentage of input genes or proteins involved in the pathway (top red in color) and the number and percentage of background genes or proteins involved in the pathway (bottom green in color). The third and fourth columns list the p-value and q-value of the statistical significance, respectively. Purine and pyrimidine metabolic pathways of (SA3) polynucleotide nucleotidyltransferase that is an RNA binding protein and involved in RNA degradation.
