Introduction: Bioinformatics integrates biology, computer science, and statistics to manage, analyze, and interpret biological data—key objectives for B. Pharm students. Core aims include sequence analysis, database retrieval, functional annotation, structural prediction, molecular docking, and pharmacogenomics to support drug discovery, target identification, and personalized medicine. Mastering tools like BLAST, GenBank, PDB, Clustal, and QSAR methods empowers pharmacy graduates to evaluate genomic and proteomic data, predict ADMET properties, and assist in rational drug design. This focused skillset enhances research, formulation, and clinical decision-making. Now let’s test your knowledge with 30 MCQs on this topic.
