What Does DNA and RNA Stand for?

DNA and RNA are acronyms that refer to deoxyribonucleic acid and ribonucleic acid, respectively. These two acids are very important and fundamental to the existence of life as we know it, because they are responsible for passing on from generation to generation and the hereditary characteristics that make that each being is what it is, as well as the characteristics that define a species.

The DNA and the RNA are found in all cells of all living beings, and in addition to the function to store, transmit, and use genetic information, are also responsible for producing protein compound that are the raw material essential to the constitution of living beings.

The DNA may also be called DNA, while the RNA can also appear as the NRA. DNA and RNA are the acronyms of the original welcome to the English language.


In DNA we find the so-called genetic code. The instructions contained in the molecules of DNA to establish itself as will be the development of a living being, as should be the operation of each part of your body and define through the genes, that contains the genetic information, which type of be alive the individual will be, a bacteria, a chicken, an elephant, a man and etc.

DNA is an organic compound which has a helical structure, that is, the format is a helix, which resembles the structure of the old telephone wires in a spiral shape. The DNA has two coiled structures that connect to each other through the nitrogen bases whose combination forms the genetic code.

The substances that make up DNA give rise to the acronym, they are: the nitrogen bases, the letter “N”; the phosphoric acid, the letter “a”; and deoxyribose, a sugar, the letter “D”. The last two components form the structure of the propeller. The bases hydrogenated are formed by adenine (A), cytosine (C), guanine (G), and thymine (T), that combined to form the genetic code or genes.


While the DNA has two coiled structures in its constitution, which are linked by nitrogen bases, RNA has only one. Where: the nitrogen bases are equivalent to the letter “N”; the phosphoric acid, the letter “a”; and ribose, a sugar, the letter “R”. And their nitrogen bases do not count with thymine (T), in its place appears the uracila (U).

The RNA is created in the nucleus of cells from the DNA, in a process known as transcription. Once it is formed, the RNA migrates to the cytoplasm where it manufactures and synthesizes protein. In the cytoplasm the RNA form molecules much smaller than those formed in the cell nucleus by the DNA.

Are identified 3 types of RNA. The RNA ribossômico and the RNA carrier, working in the production of proteins, and the messenger RNA that synthesizes proteins.
