Another early contributor to bioinformatics was Elvin A. She compiled one of the first protein sequence databases, initially published as books and pioneered methods of sequence alignment and molecular evolution. A pioneer in the field was Margaret Oakley Dayhoff. Comparing multiple sequences manually turned out to be impractical. Computers became essential in molecular biology when protein sequences became available after Frederick Sanger determined the sequence of insulin in the early 1950s.

There has been a tremendous advance in speed and cost reduction since the completion of the Human Genome Project, with some labs able to sequence over 100,000 billion bases each year, and a full genome can be sequenced for a thousand dollars or less. Sequences of genetic material are frequently used in bioinformatics and are easier to manage using computers than manually. This definition placed bioinformatics as a field parallel to biochemistry (the study of chemical processes in biological systems). Paulien Hogeweg and Ben Hesper coined it in 1970 to refer to the study of information processes in biotic systems. Historically, the term bioinformatics did not mean what it means today. In structural biology, it aids in the simulation and modeling of DNA, RNA, proteins as well as biomolecular interactions. At a more integrative level, it helps analyze and catalogue the biological pathways and networks that are an important part of systems biology. Bioinformatics tools aid in comparing, analyzing and interpreting genetic and genomic data and more generally in the understanding of evolutionary aspects of molecular biology. It also plays a role in the analysis of gene and protein expression and regulation. It plays a role in the text mining of biological literature and the development of biological and gene ontologies to organize and query biological data. In the field of genetics, it aids in sequencing and annotating genomes and their observed mutations. Image and signal processing allow extraction of useful results from large amounts of raw data. In a less formal way, bioinformatics also tries to understand the organizational principles within nucleic acid and protein sequences, called proteomics. in agricultural species), or differences between populations. Often, such identification is made with the aim to better understand the genetic basis of disease, unique adaptations, desirable properties (esp. Common uses of bioinformatics include the identification of candidates genes and single nucleotide polymorphisms ( SNPs). Bioinformatics has been used for in silico analyses of biological queries using computational and statistical techniques.īioinformatics includes biological studies that use computer programming as part of their methodology, as well as specific analysis "pipelines" that are repeatedly used, particularly in the field of genomics. As an interdisciplinary field of science, bioinformatics combines biology, chemistry, physics, computer science, information engineering, mathematics and statistics to analyze and interpret the biological data.
