Bioinformatics and Computational Biotechnology
Bioinformatics and computational biotechnology are interdisciplinary fields where bioinformatics refers to the study of large sets of biodata, biological statistics, and scientific study results. In contrast, computational biology is concerned with solutions to issues raised by studies in bioinformatics. Both fields are generally considered to be the facets of the rapidly expanding data science and biotechnology fields. They are two fields that have arisen from the growth of bioenterprises around the globe and as both fields rely on the availability and accuracy of datasets, they usually help one another reach their respective project goals. Computational biology is useful in scientific research, including how proteins interact with each other through the simulation of protein folding, motion, and interaction whereas bioinformatics includes analyzing and integrating genetic and genomic data, cheminformatic comparisons of proteins to help improve personalized medicine, and predicting protein function from data sequence and structural information.
