Bioinformatics Bioinformatics With the confluence of biology and computer science, the computer applications of molecular biology are drawing a greater attention among the life science researchers and scientists these days. As it becomes imperative for biologists to seek the help of information technology professionals to accomplish the ever growing computational requirements of a host of exciting and needy biological problems, the synergy between modern biology and computer science is to blossom in the days to come. Thus the research scope for all the mathematical techniques and algorithms coupled with software programming languages, software development and deployment tools are to get a real boost. Additionally, information technologies such as databases, middleware, graphical user interface (GUI) design, distributed object computing, storage area networks (SAN), data compression, network and communication and remote management are all set to play a very critical role in taking forward the goals for which the Bioinformatics came into existence.
