Etymologically gene comes from the Latin roots "genus", which in the royal academy determine it as "DNA sequence that constitutes the functional unit for the transmission of hereditary characters". The word gene refers to the unit of information within the genome that is the one that has all the components that are needed for its manifestation in a regulated way.
A gene, according to experts, is a series of nuclei that store the information that is needed to reduce it to a macromolecule that refers to the specific cellular role. The gene preserves the genetic documents, because they are in charge of spreading the inheritance to the descendants such as grandchildren, children, heirs, among others.
The activities of genes are very complicated because DNA is essential to acquire that functional DNA can be synthesized. On the other hand, it can be said that genetic reproduction produces a molecular RNA that can then be translated into ribosomes and generates a protein. Likewise, it can be said that they are not interpreted by proteins, because they fulfill other categories in the form of RNA.
It is important to bear in mind that genes that undergo transformation or restructuring procedures are no longer useful and would be named as pseudogenes or pseudogenes, which is a nucleotide consequence similar to that of a normal gene but does not result in a product. functional. But you can also cooperate in the growth of a species where its DNA receives change in order to produce new changes.
