A sequence logo visualizes the consensus of multiple aligned DNA, RNA, or protein sequences. At each position, letters are stacked vertically with height proportional to information content (measured in bits), and individual letter heights within the stack reflect their relative frequency. This is the standard visualization for identifying conserved positions in transcription factor binding sites, splice sites, and protein domains.
