What are the scientific and technological inventions after 1972? Great gods, help!

Bell is an English inventor. 1926 manufacturing mechanical television system. 1954 color TV was successfully piloted. The picture shows the modern TV pilot control center 1946, the first black-and-white television broadcast in the United States. The picture shows Zvorijin, an American inventor who recorded TV programs in 1950s (1889- 1982). 1923 invented the electronic TV camera tube, and 193 1 developed the TV picture tube successfully. 1906 the first electronic television image receiver made in Germany. 1868, Swiss biologist Friedrich discovered that the nucleus has two parts: acidity and protein. The acidic part was later called DNA；; 1882, when German embryologist Walter Fleming was studying salamander cells, he found that the nucleus contained a large number of divided linear objects, that is, later chromosomes. 1944, American researchers proved that DNA is the genetic material of most organisms, not protein; 1953, American biochemist Watson and British physicist Crick announced the discovery of the double helix of DNA, which laid the foundation of genetic engineering. 1980, the first transgenic mouse was born; 1996, the first cloned sheep was born; 1999, American scientists cracked the sequence map of the 22nd human genome. The future plan is to prescribe drugs for related diseases according to the genetic map.
