What does DNA Stand for

Deoxyribonucleic Acid

DNA stands for deoxyribonucleic acid, nucleic acid – in free translation for the Portuguese. It is an organic compound whose molecules contain the genetic instructions that coordinate the development and functioning of all living organisms and some viruses. The main role of the compound is to store the information needed for the construction of proteins and RNA (ribonucleic acid).

The molecular structure of DNA was discovered jointly by the American James Watson and Francis Crick in 1953 by the British, nine years after scientists were awarded the Nobel Prize of medicine.

The segments of DNA that contain the genetic information are called genes, the rest of the sequence has structural importance or are involved in regulating the use of genetic information.

The molecule is composed of a double strand of nucleotides – divided into four sub-units. The tapes come together via hydrogen bonds between the nitrogen bases. Already chains of nucleotides are made up of a pentose (five-carbon sugar) associated with one or more groups of phosphate and a nitrogenous base located within the Helix –.

The four nitrogen bases contained in the DNA are: adenine, cytosine, guanine and thymine. The bases cytosine and thymine are pyrimidines, and calls the bases adenine and guanine, purine calls.

The DNA of every individual is unique, with the exception only of twins identical twins, every human being has two forms of each gene, a maternal and paternal another. To know the paternity of a child, for example, the DNA test is the most indicated to confirm the genetic origin.
