Biotechnology - MCQ Practice Questions
Biotechnology is one of the few subjects where exam questions track laboratory practice closely, so the techniques are worth knowing in order. Practice covers recombinant DNA technology, PCR and gel electrophoresis, cloning vectors, tissue culture, fermentation and bioprocess technology, and applications in medicine and agriculture. Technique questions explain why a step exists, not just what it produces.
