Bioinformatics

Bioinformatics is a new emerging area. It is an integration of Statistics, Computer applications and Biology.   The trained manpower in the area of Bioinformatics is required for meeting the new challenges in research in the discipline of Agricultural Statistics. This course is meant to train the students on concepts of basic biology, statistical techniques and computational techniques for understanding bioinformatics principals.
