Multiple sequence alignment (MSA) of DNA, RNA, and protein sequences is one of the most essential techniques in the fields of molecular biology, computational biology, and bioinformatics. The selected region is the center block. A multiple sequence alignment (MSA) arranges protein sequences into a rectangular array with the goal that residues in a given column are homologous (derived from a single position in an ancestral sequence), superposable (in a rigid local structural alignment) or play a common functional role. It serves as the basis for the detection of homologous regions, for detecting motifs and conserved regions, for detecting structural building blocks, for constructing sequence profiles, and as an important prerequisite for the construction of phylogenetic trees.
