B.Sc Biotechnology

Hello Tushar,
A B.Tech degree in biotechnology exposes you to both the biological sciences as well as the chemical engineering principles involved in biotechnology. This degree gives students the skill sets required to find jobs in labs and industries alike.
A B.Sc degree on the other hand focuses more on the biological sciences aspect of biotechnology. Yes, there will be a few subjects (1 or 2) related to industrial processes but the main emphasis will be on R&D in biological sciences fields such as cell biology, microbiology, molecular biology, genetics, etc.
Now, what is your future goal? Do you want to pursue a research career in areas such as stem cells, genetic engineering, plant biotechnology, molecular biology? If yes, choose B.Sc and M.Sc biotechnology or B.Sc biotech and M.Sc in any specialised field of biotech that you are interested in. You can then later on pursue your PhD if interested.
If you want to keep your options open, then go for B.Tech Biotechnology. Many B.Tech students who do not find jobs in biotech sector shift to software, management etc. So, this is an added bonus for you and this kind of transition will be tougher with a B.Sc and M.Sc degree in biotechnology.
I hope this answers your question. If you have any further questions, kindly revert.
