Clustal

Clustal is a bioinformatics tool used by scientists to compare multiple DNA or protein sequences. It aligns these sequences to identify regions of similarity and difference, which can reveal evolutionary relationships or functional features. By arranging sequences side-by-side, Clustal highlights conserved areas—important parts that have remained unchanged over time—and variations. This helps researchers understand how different organisms or genes are related, how proteins might function, or how genetic traits have evolved. Essentially, Clustal organizes complex biological data to provide insights into the structure and history of genes and proteins.
