There are more contents in the new handbook of Spring Festival custom research report.

1. 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.

2. 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 yield and rich nutrients needed by human body.

3. It has a great influence on medical care, such as finding out the pathogenic genes by molecular cloning technology and putting forward the molecular biological mechanism of diseases; Seeking a wider source of organ transplantation, introducing human organ tissues and immune system genes into animals to grow the needed human organs can reduce immune rejection and improve the success rate of transplantation.

4. Protect the environment and endangered animals and plants, and propagate species through cloning technology. The fifth is to provide more suitable animals for medical research and greatly improve the accuracy and safety of the experiment.
