This page decodes the symbols you may find in your sequences and alignments. We also provide a Codon Table for translating nucleotides into amino acids.
------------------------------ Symbol Meaning -------------------------------- # frameshift ? position where no majority-rule consensus could be made X amino acid position where an IUPAC nucleotide prevented translation * stop codon $ stop codon
