Bioinformatics
  • 1. Bioinformatics is an interdisciplinary field that develops methods and software tools for understanding biological data. It combines the principles of biology, computer science, and information technology to analyze and interpret complex biological processes. Bioinformatics is crucial for studying large sets of biological data, such as genomes, proteomes, and metabolomes, to gain insights into biological systems and phenomena. By applying computational techniques, bioinformatics enables researchers to predict protein structures, analyze genetic variations, and identify potential drug targets. Overall, bioinformatics plays a key role in advancing our understanding of genetics, evolution, and disease mechanisms.
