Biotechnology comprises different sub-branches like Cell Biology, Biochemistry, Genetics, Molecular biology, Immunology, Microbial technology, Biophysical techniques, Industrial biotechnology, Environmental biotechnology, Animal/Plant biotechnology.During your biotech course, you came across different practicals of biotechnology like randomly I can say about Isolation of DNA, Gel electrophoresis AGE/PAGE, Cell culturing, Isolation of microorganism, Obtain MIC of metal, Transformation, Conjugation, BOD/COD determination etc. Whatever you have learned during the course is just a basic. If your basics are firm then only you can build up a  career in research. You should indulge yourself in different seminars or conferences held by different colleges/research institutes which gives insights about the current scenario of biotechnology research and innovations, it will also provides you a glimpse of latest tools/techniques and experiment which you have not seen during academics. Some biotech institutes like Hafikine, ACTREC in Mumbai, NCBP, IISc in Banglore, RGCB Thiruvanantpuram, CCMB Hyderabad etc provide internships, workshops for students as well as professors. You can also get a hands-on experience on expensive instruments which are used in research institutes. Only getting a biotech degree is not enough, simultaneously you have to engage yourself in small training sessions, workshops. Take an active part in biotech competitions and fests, earn certificates of participation, so that after your UG getting into job field will become little easy.

Hope It helps!!.
