Genetic gone through a breakthrough in the discovery thatDNA would be the fundamental structure carrying the genetic
information. Among the various work with this molecule, he
stood out to Watson, Crick, Wilkins, and Franklin in 1953,
which demonstrated the structure of the DNA double helix.

After the discovery of DNA structure, several other studies have
been conducted to understand who was responsible for
producing the proteins. The idea that DNA would be
responsible for the synthesis of RNA and that this, in turn,
would be responsible for producing proteins was postulated by
Crick in 1958 and became known as Molecular Biology of the
Central Dogma.

From these findings, many advances have occurred in
Molecular Biology and directly affected the development of
genetics. Among this significant progress, there is the technique
of recombinant DNA, which is characterized by the ability to
isolate a stretch of DNA and replace inside a bacterium to
produce copies of this section. Thus, it was possible to make
organisms produce substances of economic interest.

The advance of genetics completely changed the modern world,
making it possible, for example, create clones, resistant
transgenic crops to pests, perform paternity tests and solve
crimes, map diseases and perform genetic counseling.
