Sequence logos of 5′ ss (a) and 3′ ss (b), produced with the background frequencies specified as A = 0.3279, C = 0.1915, G = 0.2043, and U = 0.2763. The nucleotides whose frequencies are lower than expected are plotted upside down. The vertical bar is the information index computed as 𝑃 [ 𝑖 l o g 2 ( 𝑃 𝑖 ) ] , where 𝑃 𝑖 is the frequency of nucleotide 𝑖 ( = A , C , G o r U ) at each site.
