Background:

  • Multiple sequence alignment (MSA) is crucial for identifying conserved regions in related biological sequences.
  • Existing methods may not efficiently leverage pairwise alignments for constructing comprehensive MSAs.

Purpose of the Study:

  • To present an efficient algorithm for generating a multiple sequence alignment from a set of pairwise alignments.
  • To facilitate the identification and alignment of conserved regions within related sequence families.

Main Methods:

  • Developing an algorithm to construct a simultaneous alignment of multiple sequences based on pre-computed pairwise alignments.
  • Focusing on a natural and systematic approach derived from pairwise relationships.
