Sequence analysis is a research area that involves the study and analysis of sequences of data, such as DNA sequences, protein sequences, or text sequences. It aims to identify patterns, similarities, and differences within the sequences to understand their underlying structure, function, and evolution. Sequence analysis techniques include alignment, clustering, classification, pattern recognition, and prediction methods, among others. This area of research is essential in various fields, including bioinformatics, genomics, linguistics, and social sciences, for exploring the relationships and properties of sequential data.
