pal2nal: pal2nal (Create a codon-based DNA alignment) pal2nal: pal2nal: PAL2NAL is a program that converts a multiple sequence alignment pal2nal: of proteins and the corresponding DNA (or mRNA) sequences into pal2nal: a codon-based DNA alignment. The resulting codon-based DNA pal2nal: alignment can further be subjected to the calculation of pal2nal: synonymous (Ks) and non-synonymous (Ka) substitution rates. pal2nal: pal2nal: Home: http://www.bork.embl.de/pal2nal/ pal2nal: pal2nal:
