Fig. 3From: Genomic identification and functional analysis of essential genes in Caenorhabditis elegansThe percentage of different essentiality genes locate in TAD boundaries. The four groups are labelled in black, red, green, and blue, respectively. Statistical difference was calculated for G1 vs. G2, G3, and G4 individually by using Fisher’s exact test (* P-value < 0.05, ** P-value < 0.01, *** P-value < 0.001)Back to article page
