bioinformatics
This computerized image of anthrax shows the various structural relationships of seven units within the protein and demonstrates the interaction of a drug (shown in yellow) bound to the protein to block the so-called lethal factor unit. Bioinformatics plays an important role in enabling scientists to predict where a drug molecule will bind within a protein, given the individual structures of the molecules.
While the terms bioinformatics and computational biology are often used interchangeably, experts distinguish them based on their primary focus and methodology.1
- Bioinformatics is primarily concerned with data management and analysis. It involves the collection, storage, and curation of biological data—such as genomic sequences—using computational tools to support biological experimentation and the interpretation of laboratory results.123
- Computational biology is considered a distinct branch of biology, analogous to how computational physics is a branch of physics. It focuses on using computer science techniques to model biological systems, simulate processes, and formulate or test scientific hypotheses.1
In essence, while both fields rely on computational approaches to study life, bioinformatics acts as an aid to experimental biology through data processing, whereas computational biology uses computation to fundamentally understand and model the structures and processes of living organisms. Many professionals feel that these distinctions are not always useful, as the two fields are deeply interconnected and frequently overlap in practice.1
