Bioinformatics is conceptualizing biology in terms of molecules (in the sense of physical-chemistry) and then applying “ informatics ” techniques (derived from disciplines such as applied math, CS, and statistics) to understand and organize the information associated with these molecules, on a large-scale. • Bioinformatics is “MIS ...
