Genetic gone through a breakthrough in the discovery that

DNA 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.
