Hello,

Elegibility criteria for Mtech in bio technology is Btech or (bsc+msc). So if you have completed  b.sc in biotechnology then you should persue m.sc in biotechnology to be eligible for M tech in biotechnology

So by completing M.sc in biotechnology you can directly apply to jobs too or if you want to enter RnD of companies doing an Mtech after you M.sc will be the best option
