Clustal X is a sequence alignment tool that is used to compare multiple DNA, RNA, and protein sequences. It uses the Clustal algorithm to align sequences and can easily be run as a stand-alone application or web-based application. It is an essential tool for bioinformatics research, as it can help to identify patterns, relationships and similarities between sequences. It can also be used to predict the structures of proteins, and to detect conserved regions in a multiple sequence alignment. For example, Clustal X can be used to compare two or more genes, identify conserved regions between gene sequences, and generate phylogenetic trees. Clustal X also has a graphical user interface, and it can be used to view multiple alignments, color-coding sequences, and adjusting parameters.
Discontinued The program is no longer maintained. The latest version, 7.2.5, released in December 2013, can still be downloaded from the official website.
