Insulin is a potent drug for treating diabetes. For a long time, it could only be extracted from the pancreas of animals such as pigs and cows, with low production and high costs. Microorganisms grow rapidly and are easy to control. Therefore, scientists imagine that if the human insulin gene can be introduced into microorganisms and expressed, it will not only solve the problem of production but also greatly reduce production costs, leading to a significant reduction in drug prices. Imagine 2 Can microorganisms produce valuable drugs such as human insulin? Can these targeted genetically modified gene ideas be realized? After years of effort, scientists finally established a new technology for targeted bioengineering - genetic engineering The concept of genetic engineering: refers to the strict design according to people's wishes and through in vitro DN...
