Introduction to Bioinformatics

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.
