Supplementary Table 4: The top 10 biological process Gene Ontology (GO) categories that are significantly over- or under-represented near the mammalian CNCs. For each CNC, the nearest gene was found without considering gene orientation. The first column (Key) shows the nested relationship between GO categories. For example, 22_8 has level of 2 and is nested in 22, which has level of 1. The second column (Obs) is the observed count of genes near CNCs in each category. The third column (Exp) is the expected count genes near CNCs that are obtained based on the distribution of all human genes. The fourth column indicates if each GO category is over- or under-represented. One-sided p-values are computed using a chi-square test and are corrected by the Bonferroni criterion (p*values), using the number of the GO categories that are tested in each level.
