Bioinformatics is an interdisciplinary field that merges biology, computer science, and information technology. It is applied in areas like genomics, proteomics, and systems biology. While some basic analysis can be done through user-friendly tools, truly customized work requires programming skills and an understanding of underlying algorithms. Bioinformatics is not just a service field but rather involves scientific experimentation throughout the entire analysis process from experimental design to evaluation. It is a dedicated field of research in its own right, not a quick or interchangeable task.
