From: Characterization and expression patterns of let-7 microRNA in the silkworm (Bombyx mori)
Sequence logo of known let-7 family members. Ninety known let-7 members together with bmo-let-7 were aligned using the CLUSTAL × program, then were submitted to logo analysis by using the WebLogo program available [66]. The height of the letters indicates the relative frequency of the letter at that position and the overall height of the stack indicates the sequence conservation in terms of information content in bits.
