Concept in Definition ABC

DNA is the deoxyribonucleic acid responsible for containing all the genetic information of an individual or being alive, information that is unique and unrepeatable in each being since the combination of elements is constructed in a only.

This acid also contains the genetic data that will be hereditary, that is, that will be transmitted from one person to another, according to generation to generation, for which its analysis and understanding turns out to be of great importance to carry out any type from investigation scientific or venture a hypothesis what to see on the identity or about the characteristics of an individual.

The information that deoxyribonucleic acid or DNA offers us is that which is directly linked to the conformation of any type of cell in a living being. This information is transported through the segments known as genes, constructions responsible for shaping the different cell complexes of an organism.

It is worth mentioning that according to the

complexity that a living organism presents, the DNA may be more or less complex, that is, it may present more or less information. In this sense, the DNA of individuals is much more complicated than that of a bacterium, which has a single chromosome, to cite an example.

DNA could be described as a complex chain of polymers (or macro cells), polymers that are doubly interwoven through hydrogen bonds. The structure of DNA becomes more complex from the pairs of nucleotides, forming histones, nucleosomes and the chromatids that make up the famous chromosomes. Chromosomes are located in the nucleus of a cell and their specific combination is what determines the gender of the living being: male or female, male or female.

It is worth noting that in the case of human beings, gender is determined in the so-called pair 23, being female if the pair is XX, and male if the XY combination exists. Chromatids are then composed of this entire chain of elements that begins with DNA.

Biological influence of DNA

DNA stores information about genes, the genome, and is also responsible for encoding protein and to replicate the same DNA in order to guarantee that the transfer of information to the new cells takes place while the division lasts mobile. Without DNA, the information that builds or sustains a certain organism would not be viable, let alone the impossibility of transmitting the information we mention.

Transmission of the inheritance genetics

The gene is the name that designates that DNA sequence that ensures that those aspects and characteristics that come from inheritance are transmitted from generation to generation in a satisfactory. The gene has the information that is considered inheritance and that men and women pass on to all their descendants throughout life. Now, it should be noted that this information includes physical aspects such as brown and blue eyes and the tendency to having a tummy, as well as any other type of situation plausible to be inherited, such as a predisposition to some condition or disease.

Benefits of DNA knowledge and research

The discovery, analysis and understanding of DNA have enabled humans to perform all kinds of research and scientific advances that aim to improve the living conditions of beings alive. Among these elements we must mention the achievements in genetics and forensic investigations, for example, at present, it is possible to determine the material responsibility of a crime if it is that in the scene samples of genetic material can be obtained from it. And not to mention in the matter of resolution of some affections, since the millimeter knowledge of the composition of an individual It also allows us to know its deficiencies and with the imprint of science to look for alternatives that allow the cure of diseases.

Also in computing It has been relevant since in systems of this type some elements related to the composition of DNA are applied.

Undoubtedly, by fully deciphering the composition of DNA, the human being produced one of the most important in history, being able to have access to the same compositional structure of each individual at the genetic.
