Figure 5

GC content and length distribution of 3' UTR sequences. Shown is the density distribution of GC content and length in the set of all 3' UTR sequences, in the set of predicted human "Vari" targets of at least three Dlk1/Gtl2 microRNAs and in the set of human antitargets of at least 16 Dlk1/Gtl2 microRNAs. The frequencies of the bins are normalized to equal one for each set of sequences (density distribution), which corrects for the different number of sequences in each set. For a better visualization of the 3' UTR length, the natural logarithm of the length was used.
