Biotechnology is a combination of two subjects- Biology and Technology. Broadly speaking, it brings together concepts of Biology and Engineering and aims at putting concepts of both these subjects together, in a bid to enrich our lives and make innovative developments.
Biotechnology course material can be classified into two sections- theory section and practical section. In theory section, students will have to deal with subjects related to biology as well as basic technology concepts.
Practical section is also very important. Students will have to spend good amount of time in laboratory, performing practical lessons as well as lab training.
At the end of the course, research project is also held. Lab activities form a major part of project.
