The day of the discovery of the uniqueness of DNA

The discovery of the DNA molecule was made very recently. In 1953, its existence was predicted by two scientists — Francis Crick and James Whartson. However, Alec Jeffries was able to discover the uniqueness and uniqueness of this spiral structure much later, namely on September 3, 1984. Since then, this day is celebrated every year in the world The day of the discovery of the uniqueness of DNA.

This discovery had a truly global significance. It brought genetics and forensics to a qualitatively new level. Also, with the discovery, such a field as genetic dactyloscopy began, and with the help of genetic prints it became possible to determine paternity, involvement in a crime, help in correcting judicial errors, due to which innocent people were put behind bars. One hair, drop of blood or saliva is enough to identify a person.

The discovery of the uniqueness of DNA also made it possible to make a breakthrough in historical research. With the help of DNA analysis, scientists are able to investigate the origin of entire nations.

• It was extremely interesting to establish the fact that the genes of the inhabitants of Japan are almost 100% identical to the genes of one of the Central American tribes.

Further research on DNA gives great promise in medicine. If it is possible to make changes in human genetics, then it is possible to completely rid humanity of genetic diseases, cancer, etc.
