Answer:
In the DNA structure all the genetic information of a living being is stored and through the replication of the DNA this information is transferred from one generation to another, which allows the reproductive inheritance.
Step-by-step explanation:
DNA is a molecule composed of two thin strands of filiform polymers that intertwine with each other and form a regular double helix structure. Each chain is a poly-nucleotide (polymeric grouping of nucleotides), which are made up of: a pentose-type sugar called deoxyribose; a nitrogen base and a phosphoric acid group. This nucleic acid contains the information of the inherited characteristics of each living being and the sequences for the creation of amino acids that will generate the vital proteins for the functioning of organisms.
The nitrogen bases of DNA can be of four types: adenine (A), cytosine (C), thymine (T) or guanine (G), together with a phosphate group. In the sequence of this compound, all the genetic information of a living being is stored, essential for protein synthesis and for reproductive inheritance, that is, without DNA there would be no transmission of genetic characters.
DNA replication occurs before the cell divides and consists of obtaining identical copies of the fundamental cellular information for transfer from one generation to another, thus constituting the basis of genetic inheritance.
