Learn to use the ClustalW2 resource at the EBI Toolbox site for performing multiple sequence alignments, or MSA. MSA allow us to analyze the evolutionary relationship between species on a molecular sequence level. As well, multiple sequence alignments can help us to identify functionally important positions in a sequence family by simply looking at the conservation of positions or motifs within the sequence data.
