PPT-Multiple alignment The linear comparison of more than two sequences

Places residues in columns per position specific similarity scores reflects relationships of the sequences the scores are based on indels gaps and substitutions The alignment of residues implies that they have similar roles in the proteins or DNA sequences being aligned .
