By using biotechnology, we can not only cultivate high-quality, high-yielding, and resistant crops and new varieties of livestock and poultry, but also cultivate animals and plants with special uses.

Biotechnology and Medicine and Health

Production of genetically engineered drugs

Many pharmaceuticals are produced from biological tissues. Due to limited material sources, the output is limited, and the price is often very expensive.

Microorganisms grow rapidly and are easy to control, making them suitable for large-scale industrial production. If the genes for biosynthesizing corresponding drug components are introduced into microbial cells and allowed to produce the corresponding drugs, it will not only solve the yield problem, but also greatly reduce production costs.
