Biotechnology is a technology- based biology course. It is multidisciplinary area encompassing not only Biology and Engineering but also subjects such as Chemistry, Physics and Mathematics. Generally institutes offer B.Tech and B.Sc programmes in this discipline. The curriculum of 4-year B.Tech course focuses on technological applications of biology whereas the 3/4-year B.Sc course curriculum has science subjects such as Biology, Chemistry and Maths followed by subjects related to biotechnology. If one wants to become a scientist, then he/ she can consider both options but it is advisable to go for a B. Tech in Biotechnology rather than pursuing a B. Sc as after B. Tech in Biotechnology, you will be directly eligible for CSIR-NET exam. In case of a three/four- year course, you will have to do a M. Sc for CSIR- NET. The B. Tech course will also save you a year, which is a better option. Selection for B. Tech course is based on engineering entrance exams and marks obtained in your 10+2 or equivalent examination in science subjects. Another options is to go for 5-year integrated B. Sc- M. Sc in Biotechnology.
