To pursue biotechnology after your 10+2 you can choose the following courses for further studies: btech/be in biotechnology/ bsc in biotechnology. There are many specializations that are offered by different colleges to pursue biotech, a few common ones are: Microbiology, Molecular Biology, Cell Biology, Genetics, etc., and Engineering subjects such as Bio Process Eng., BioChemical Eng., Thermodynamics, Mass Transfer (for be/btech ) & Biochemistry, Plant Biotechnology, Animal Biotechnology, Microbiology, dairy technology, virology (for bsc ).

Bsc degree is mainly for research & development oriented jobs.
