Study Notes
Bioinformatics Analysis
- Bioinformatics combines biology and information technology.
- It's a relatively new science utilizing information to understand biological phenomena.
- It uses computational tools and methods to manage, analyze, and manipulate large volumes of biological data.
- It's considered a part of computational biology.
- Bioinformatics focuses on the application of quantitative analytical techniques to model and solve biological system problems.
- Bioinformatics is an interdisciplinary field requiring advanced computer mathematics and statistical methods for understanding biological phenomena at the molecular level.
History of Bioinformatics
- Bioinformatics emerged in the 1990s.
- Early bioinformatics focused on managing and analyzing DNA, RNA, and protein sequences.
- Bioinformatics now encompasses many other types of biological data, including:
- Gene expression profiles
- Protein structure
- Protein interaction
- Microarrays (DNA chips)
- Functional analysis of biomolecules
- Drug designing
Broad Coverage of Bioinformatics
- Functional genomics: identifies genes and their respective functions.
- Structural genomics: predicts protein functions.
- Comparative genomics: studies the genomes of different species.
DNA Microarrays
- Designed to measure gene expression levels in different tissues and at various stages of development or disease.
Medical Informatics
- Manages biomedical data with a focus on biomolecules, in vitro assays, and clinical trials.
Components of Bioinformatics
- Databases: organize, store, and manage biological data sets; accessible databases for submitting entries, such as protein sequences and molecular structure.
- Algorithms and Statistics: develop tools and resources for analyzing the relationships between large datasets (e.g., comparing protein sequence data with existing sequences).
- Data Interpretation: analysis of DNA, RNA and protein sequences, protein structures, gene expression profiles and biochemical pathways.
Bioinformatics and the Internet
- Bioinformatics utilizes an international computer network (internet).
- Computers communicate to exchange information and data.
- Internet protocols determine how information packets are addressed and routed.
- Proper hardware, software, and access permission are needed to access the internet.
Applications of Bioinformatics
- Sequence mapping of biomolecules (DNA, RNA, and proteins).
- Identification of functional gene nucleotide sequences.
- Location of restriction enzyme cut sites.
- Prediction of functional gene products.
- Tracing evolutionary trees of genes.
- Predicting 3-dimensional protein structure.
- Molecular modeling of biomolecules.
- Drug design.
- Managing vast biological data which otherwise would be impossible to manage.
- Developing models for the functioning of cells, tissues, and organs.
