Biotechnology, agriculture, animal husbandry, and food industry

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.

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.

Pay attention to biotechnology PPT, part 2: safety of biotechnology

Does the development of biotechnology bring benefits to mankind?

think

1. The rapid advancement of biotechnology makes it possible for people to create new types of organisms according to their own wishes. In particular, the success of cloning mammals has led some scientists to come up with a bold idea: cloning humans. Please talk about your views on "human cloning" based on your own knowledge and briefly state the reasons.

2. Genetically modified technology can greatly increase the yield and quality of crops such as tomatoes and corn, but it also changes the original genetic composition of these organisms. Therefore, some people think that genetically modified foods cannot be used. What do you think about this?
