For your better test preparation and better Biology MCQs preparation, in this section, we are posting Biotechnology MCQs.
Biotechnology is the branch of biology involving living systems and organisms to develop or make products. Biotechnology can also be described as any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use.
Biotechnology involves the exploitation of biological processes for industrial and other purposes, especially the genetic manipulation of microorganisms for the production of antibiotics, hormones, etc.
