Biotechnology Mcqs

This Set of Multiple choice questions and answers focuses on study of Biotechnology in Biology. These questions are chosen from a collection of most authoritative and best reference books on Biology. Our aim is to prepare an individual for competitive exams like NTS, GAT, ECAT, MDCAT, Teaching jobs Tests and Medicine industry job interviews. One should practice our Mcqs to assimilate knowledge on Biotechnology comprehensively.
