Figure 2

Nucleotide composition difference between conserved and non-conserved pre-miRNAs. The A, U, G, and C composition difference between conserved (Sc1, Sc2, and Sc3) and non-conserved pre-miRNAs (Sn) from human (A), mouse (B), and chicken (C) genomes. The white, gray, and black bars respectively denote the values that Sc1, Sc2, and Sc3 mean nucleotide compositions minus that of Sn. Sc1 for chicken was excluded as it contained fewer than five pre-miRNAs.
