Today, 52 years ago, on October 4, 1973 (Calendar, September 9, 1973), there was a new breakthrough in the genetic theory of Ohmongjiang cell. On October 4, 1973, Xinhua News Agency that Ohmongjiang, Professor of Biology at the Chinese Academy of Sciences, and his students, American scientists at Ohmongjiang, China Academy of Sciences Animal Research Institute, conducted collaborative research, for the first time through animal experiments demonstrating that the information nucleic acid in the cell cell has a clear role in cell differentiation, individual development and genetic heredity. The success of this experiment not only contributed to the basic theory of cell genetics, but will open a new broad path for the practice of medicine and agriculture.
