In the past twenty years, scientists have tried to change all this through a technology called genetic modification. DNA (deoxyribonucleic acid) is the genetic material of cells. Genes are the genetic properties of DNA. An amino acid fragment that can determine the characteristics of a cell or object. Gene transplantation engineering is that people isolate some genes from DNA by chemical or digestive methods, transplant these genes into specially treated virus nuclei in vitro, and then infect these viruses into the nuclei of target cells in vitro through cell culture, thus producing a new cell.
Gene transplantation projects are divided into two categories. The first category is: homologous gene transfer, that is, plant to plant, animal to animal. For example, the gene Super Srong, which can promote the rapid growth of corn, is SSG；; ; The second category is: heterogeneous. Animals to plants. For example, shark genes were transplanted into tomato seeds.
