The pace at which scientific data is produced and disseminated has never been ashigh as it is currently. Modern sequencing technologies make it possible to obtain the genomeof a specific organism in a few days, and the genome of a bacterial organism in less than a day,and therefore researchers from the field of life science are faced with a huge amount of datathat needs to be analyzed. In this connection, various fields of science are converging with eachother, giving rise to new disciplines. So, bioinformatics is one of these fields, it is a scientificdiscipline that has been actively developing over the past decades and uses IT tools andmethods to solve problems related to the study of biological processes. In particular, a crucialrole in the field of bioinformatics is played by the development of new algorithms, tools andthe creation of new databases, as well as the integration of extremely large amounts of data.The rapid development of bioinformatics has made it possible to conduct modern biologicalresearch. Bioinformatics can help a biologist to extract valuable information from biologicaldata by using tools to process them. Despite the fact that bioinformatics is a relatively newdiscipline, various web and computer tools already exist, most of which are freely available.This is a review article that provides an exhaustive overview of some of the tools for biologicalanalysis available to a biologist, as well as describes the key role of information systems in thisinterdisciplinary field.
