Study Notes
Introduction to Bioinformatics
- Bioinformatics is an interdisciplinary field combining computer science, statistics, and mathematics with biology to analyze biological data.
- Computational tools analyze large biological datasets like DNA sequences, protein structures, and gene expression profiles.
- The goal is to understand biological processes and systems.
Key Areas of Bioinformatics
- Genomics: Studies the structure, function, and evolution of genomes, including sequencing, assembly, annotation, and comparative genomics.
- Proteomics: Studies protein structure, function, and interactions, including identification, quantification, and interaction mapping.
- Transcriptomics: Studies gene expression patterns using RNA sequencing and gene expression analysis in cells or organisms.
- Metabolomics: Analyzes small-molecule metabolites, identifying, quantifying, and analyzing metabolic pathways.
- Bioimage Analysis: Analyzes biological images (microscopy, medical scans) computationally, expanding on traditional manual observations.
Bioinformatics Tools and Techniques
- Sequence Alignment: Compares biological sequences (DNA, RNA, protein) to identify similarities and differences.
- Phylogenetic Analysis: Reconstructs evolutionary relationships between species using sequence comparisons.
- Gene Prediction: Computes methods identifying protein-coding genes in DNA sequences.
- Structural Bioinformatics: Studies 3D protein and nucleic acid structures and their relationship to function.
- Data Mining and Machine Learning: Identifies patterns and relationships in biological datasets to gain knowledge and make predictions using algorithms.
- Databases: Essential for storing biological information (protein sequences, structures, annotations) like GenBank, UniProt, and others.
- Software Packages: Critical tools for handling and analyzing biological data such as BLAST, Clustal Omega, and various bioinformatics suites.
