See if you are willing to take basic science as your career then you have to do MSc as a must. Now Integrated MSc is a great option as you have not to worry about any more entrances and you can focus on your curriculum. But I would say Integrated MSc Biotechnology in Sastra University isn't worth because I feel the curriculum isn't organized and have lesser industrial relevancy. I would suggest you to go for BSc Biotechnology and then after BSc you can write IIT-JAM to do your Masters. This way you will be able to make your future brighter.

I hope my answer helps. All the very best for your future endeavors!
