Lecture 04: Data Retrieval from Biological Databases (NCBI, UniProt & PDB) | Biocode Innovators

Welcome to Lecture 04 of the Free Bioinformatics Bootcamp 2026, organized by BioCode Innovators. In this session, we will learn how biological information is retrieved from the world's most widely used public databases. Data retrieval is the foundation of every bioinformatics workflow, enabling researchers to access gene sequences, protein information, scientific literature, and three-dimensional protein structures for downstream analysis. During this lecture, you will gain hands-on knowledge of navigating and retrieving biological data from NCBI, UniProt, and the Protein Data Bank (PDB). We will also explore common biological data formats and understand how accession numbers and database queries are used to locate reliable biological information. 📖 Topics Covered -Introduction to Biological Data Retrieval -NCBI Entrez Gene & PubMed -UniProt Protein Database -Protein Data Bank (PDB) -Sequence Retrieval -Protein Structure Retrieval & Visualization -Biological Data Formats (FASTA, PDB & XML) -Database Queries and Accession Numbers -Best Practices for Retrieving Biological Data Whether you are beginning your journey in bioinformatics or strengthening your understanding of biological databases, this lecture will provide the essential knowledge required for future topics such as sequence alignment, structural biology, molecular docking, and computational genomics.
