Study Notes
Bioinformatics Explained
- The application of computational and analytical tools to interpret biological data.
- Combines computer science, biology, physics, chemistry, and statistics.
- Aims to solve biological problems, understand biological processes, and utilize information technology for biological solutions.
- Focuses on storing, retrieving, and analyzing massive biological information.
Bioinformatics: An Interdisciplinary Field
- Involves diverse areas like science, medicine, and future technologies.
- Essential for analyzing "big data" derived from biological sources.
Human Genome Analysis
- Contains approximately 20,000 protein-coding genes.
- Surprisingly, only 2% of the human genome codes for proteins.
- The remaining 98% consists of regulatory elements and non-coding RNA genes.
Analyzing Large Data Sets
- Bioinformatics techniques are designed to identify:
- Transcriptomes: Complete sets of RNA molecules produced by a genome, revealing gene expression patterns.
- Proteomes: The structures and properties of all proteins produced by a genome.
Bioinformatics Centers of Excellence
- Global presence, responsible for collecting, cataloguing, and providing open access to biological data.
- These centers originated in the early 1980s, as DNA sequence data accumulation grew.
Key Bioinformatics Centers
- The European Bioinformatics Institute (EMBL-EBI)
- The US National Center for Biotechnology Information (NCBI)
- The National Institute of Genetics in Japan (NIG)
- The Barcode of Life Data System (BOLD)
Biological Databases
- Organized collections of structured, searchable, regularly updated, and cross-referenced biological information.
NCBI: National Center for Biotechnology Information
- An international repository for biological data, known for its advancements in science.
What is Bioinformatics?
- Bioinformatics is the application of computing and analysis tools to interpret biological data.
- It is an interdisciplinary field that incorporates computer science, biology, physics, chemistry, and statistics.
- Its primary goal is to understand biological processes, solve biological problems, and find solutions using information technology.
- Bioinformatics deals with large amounts of biological information, making it a vital field for analyzing and interpreting data.
Bioinformatics: A Science of Big Data
- The human genome contains approximately 20,000 protein-coding genes.
- This is slightly more than a worm, around twice the number of a fruit fly, and 12,000 less than a rice plant.
- Less than 2% of the human genome actually encodes proteins.
- The remaining 98% contains crucial regulatory elements and genes that encode non-coding RNA products.
Bioinformatics Techniques for Analyzing Big Data
- Bioinformatics techniques are designed to identify and analyze:
- Transcriptomes: The complete set of RNA molecules produced by a genome, revealing gene expression.
- Proteomes: The structure and properties of every protein produced by a genome.
Bioinformatics Centers of Excellence
- Centers of excellence for bioinformatics are found worldwide.
- They are responsible for collecting, cataloguing, and providing open access to published biological data.
- This work began in the early 1980s, when DNA sequence data started to accumulate in scientific literature.
Examples of Bioinformatics Centers of Excellence
- EMBL-European Bioinformatics Institute (EMBL-EBI)
- US National Center for Biotechnology Information (NCBI)
- National Institute of Genetics in Japan (NIG)
- Barcode of Life Data System (BOLD)
Biological Databases
- Biological databases are structured, searchable, periodically updated, and cross-referenced collections of data.
- These collections are essential for storing, retrieving, and analyzing large amounts of biological information.
