First, using biotechnology such as cloning to change the genotype of crops and produce a large number of new varieties with disease resistance, insect resistance and salt tolerance, thus greatly improving the yield of crops.
The second is to cultivate a large number of excellent livestock, such as cattle, sheep and pigs with good meat quality, and also cultivate some cows with high milk production and rich nutrients needed by human body.
Third, it has great influence on medical treatment, such as finding out the pathogenic genes by molecular cloning technology and putting forward the molecular biological mechanism of diseases; Cloning a transgenic sheep whose milk contains drug protein for treating hemophilia can better meet the dietotherapy needs of hemophilia patients.
Fourth, in order to protect the environment and endangered animals and plants, species are propagated through cloning technology.
The fifth is to provide more suitable animals for medical research and greatly improve the accuracy and safety of the experiment.
