Phylogenetic Tree Building

This page enables you to build phylogenetic trees from sets of nucleotide sequences and from sets of protein sequences, using the buttons below.

• When building trees from nucleotide sequences, this first, simpler-to-use form assumes that every sequence you provide is a nucleotide coding region.

  Nucleotide Coding Regions

  This second form enables you to specify a set of arbitrary nucleotide sequences that do not correspond to coding regions.

  Arbitrary Nucleotide Sequences

• This button enables you to build phylogenetic trees from a set of protein sequences.
