Bioinformatics is defined as the field that studies biology using computers and information technology. It involves the collection, storage, and analysis of molecular biological data. Some key events in bioinformatics history include Watson and Crick proposing the DNA double helix structure in 1953 and the development of databases like GenBank and algorithms like BLAST and FASTA in the 1980s to aid in database searching. The goals of bioinformatics are to better understand living cells at the molecular level by analyzing raw molecular data. It has become important due to the explosive growth of biological data and need for large databases and tools to access and study this information.
