An Overview of Multiple Sequence Alignment Systems

We care about the sequence alignments in the computational biology because it gives biologists useful information about different aspects. For example, it can tell us about the evolution of the organisms, we can see which regions of a gene (or its derived protein) are susceptible to mutation and which can have one residue replaced by another without changing function, we can study Homologous genes and can uncover paralogs and Orthologs genes that are evolutionary related.
