Introduction to Bioinformatics

Bioinformatics is a multidisciplinary field that combines biology, computer science, and statistics to analyze and interpret biological data. It involves the development and application of computational methods and tools to gather, store, organize, and analyze large volumes of biological data, such as DNA sequences, protein structures, gene expression patterns, and more.

The main goal of bioinformatics is to extract meaningful information from biological data to gain insights into various biological processes, understand the relationships between genes and proteins, and explore the underlying mechanisms of diseases. Bioinformatics plays a crucial role in genomics, proteomics, evolutionary biology, drug discovery, and personalized medicine.

Bioinformatics utilizes various computational techniques, including algorithms, data mining, machine learning, and statistical modeling, to process and analyze biological data. It involves tasks such as sequence alignment, gene expression analysis, protein structure prediction, functional annotation, comparative genomics, and systems biology.

Researchers and bioinformaticians in this field use specialized software and databases to store and retrieve biological information. They also develop algorithms and software tools to analyze and interpret the data, enabling researchers to make new discoveries and generate hypotheses for further experimental validation.

Overall, bioinformatics has revolutionized the way biological research is conducted by enabling scientists to extract valuable insights from vast amounts of biological data and accelerate discoveries in fields such as genetics, molecular biology, and medicine.

Definition of Bioinformatics

Bioinformatics Definition -General view

Bioinformatics derives knowledge from computer analysis of biological data. These can consist of the information stored in the genetic code, but also experimental results from various sources, patient statistics, and scientific literature. Research in bioinformatics includes method development for storage, retrieval, and analysis of the data. Bioinformatics is a rapidly developing branch of biology and is highly interdisciplinary, using techniques and concepts from informatics, statistics, mathematics, chemistry, biochemistry, physics, and linguistics. It  has many practical applications in different areas of biology and medicine.

Roughly, bioinformatics describes any use of computers to handle biological information. In practice the definition used by most people is narrower; bioinformatics to them is a synonym for “computational molecular biology”- the use of computers to characterize the molecular components of living things.

Bioinformatics Definition -Personal view

The mathematical, statistical, and computing methods that aim to solve biological problems using DNA and amino acid sequences and related information.

The Loose definition

There are other fields-for example medical imaging / image analysis which might be considered part of bioinformatics. There is also a whole other discipline of biologically inspired computation; genetic algorithms, AI, neural networks. Often these areas interact in strange ways. Neural networks, inspired by crude models of the functioning of nerve cells in the brain, are used in a program called PHD to predict, surprisingly accurately, the secondary structures of proteins from their primary sequences. What almost all bioinformatics has in common is the processing of large amounts of biologically derived information, whether DNA sequences or breast X-rays.

Bioinformatics definition by bioinformatics definition Committee, National Institute of Mental Health released on July 17, 2000 (source:  http://www.bisti.nih.gov/ ) (1)

The NIH Biomedical Information Science and Technology Initiative Consortium agreed on the following definitions of bioinformatics and computational biology recognizing that no definition could completely eliminate overlap with other activities or preclude variations in interpretation by different individuals and organizations.

Bioinformatics: Research, development, or application of computational tools and approaches for expanding the use of biological, medical, behavioral or health data,including those to acquire, store, organize, archive, analyze, or visualize such data.

Computational Biology: The development and application of data-analytical and theoretical methods, mathematical modeling and computational simulation techniquesto the study of biological, behavioral, and social systems.

The National Center for Biotechnology Information (NCBI 2001) defines bioinformatics as “Bioinformatics is the field of science in which biology, computer science, and information technology merge into a single discipline.There are three important sub-disciplines within bioinformatics: the development of new algorithms and statistics with which to assess relationships among members of large data sets; the analysis and interpretation of various types of data including nucleotide and amino acid sequences, protein domains, and protein structures; and the development and implementation of tools that enable efficient access and management of different types of information.”

Bioinformatics- Definition (As submitted to the Oxford English Dictionary)

(Molecular) bio informatics: bioinformatics is conceptualising biology in terms of molecules (in the sense of Physical chemistry) and applying informatics techniques(derived from disciplinessuch as applied maths, computer science and statistics) to understand andorganise the information associatedwith these molecules, on a large scale. Inshort, bioinformatics is a managementinformation system for molecular biology and has many practical applications.
