Figure 2From: TFCONES: A database of vertebrate transcription factor-encoding genes and their associated conserved noncoding elementsPlot of CNE density against the total length of CNEs associated with DNA-binding TF-encoding genes. CNE density is defined as the number of bases located in CNEs per unit length (1 kb in human; 100 bp in fugu) of non-repetitive noncoding sequence in a gene locus.Back to article page
