Computer-generated model of anthrax toxin showing seven differently colored protein units, with a small gold molecule representing a drug bound to the protein structure. — 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.

Alan Turing, often recognized as the father of computing, made foundational contributions to the early development of computational biology in the early 1950s. Shortly before his death, he utilized early computers to implement a model of biological morphogenesis, which describes the development of pattern and form in living organisms.1

This work is considered one of the first instances of authentic computational modeling in biology, marking a significant shift toward using computer science to simulate and understand biological systems. While other early applications of computers in the 1950s focused on numeric calculations for population genetics, Turing’s approach demonstrated how computational methods could be applied to represent complex biological processes. His pioneering efforts helped establish the intersection of these fields, laying the groundwork for modern computational biology.1
