Computer science is relevant to the field of biotechnology in many ways, especially in the area of bioinformatics – the aspect that involves the development of software tools and methods for understanding biological data. Being able to visualize, simulate, and analyze biological and genetic information is made possible by the applications of computer science. Drug discovery relies on algorithms that "map" chemicals onto protein structures. Increasingly, artificial intelligence and machine learning are being used to predict disease from diagnostic information and develop new therapies. Other aspects of using computers in biotechnology include managing laboratory information and using office software (word processing, spreadsheets, and presentation tools) for general work.
