In [[Bioinformatics]], multiple alignment can be used to study [[evolutionary]] relationships between related [[proteins]]. Since the changes between gene sequences due to evolution are incremental, we can take homologous genes , i.e. genes with a common evolutionary origin, from a diverse range of organisms and then compare them by aligning identical or similar [[residues]]. The comparison of these related genes may then be used to study, which regions of genes have been conserved, and which are sensitive to [[mutation]], over the years. This is very useful in designing experiments to test and modify the function of specific proteins, and to predict the function and [[protein structure|structure of proteins]], and to identify new members of protein families.
