Mating is the act and effect of mating.
Mating is the act and result of mating , a verb that can refer to different issues: bringing together males and females to have offspring, bringing together two elements to form a pair or arranging different objects so that they are equal.
If we focus on the field of biology , the notion of mating covers the behaviors and actions that two specimens of different sex carry out for the development of procreation . Mating, in this context, ends in copulation .
Courtship and mating
It is important to highlight that before reaching this last step, which consists of the action that the male performs to inseminate the female , which is usually described with the term penetration , mating is a broader set, in which we also find the different forms of courtship .
Courtship is a process that begins with the selection of an individual with the aim of maintaining intimate relations with it, and the subsequent behavior to attract it. Although this term is currently used especially to talk about animal species , it is also used by humans.
Animal species, to reproduce, develop mating naturally. However, in some cases, man intervenes in reproduction and leaves mating aside. This occurs when artificial insemination of livestock is used, for example. In these cases, the animals do not mate to have offspring .
Mating is associated with procreation.
Structuring of sexual behaviors
The structuring of sexual behaviors is known as the mating system . Bonds can occur within the framework of monogamy or polygamy , depending on the species.
In the case of humans , the mating system is very broad since there are multiple types of relationships. Humans also usually develop sexual relations without reproductive purposes.
base pairing
The idea of mating also appears in other areas that are not linked to sexuality. Base pairing is an interaction established by nitrogenous bases that allows the hybridization of ribonucleic acid ( RNA ) and deoxyribonucleic acid ( DNA ).
To achieve the emergence of said folded or hybridized forms of nucleic acids, it is necessary that certain well-defined regions interact. The well-known scientists Francis Harry Compton Crick and James Dewey Watson , natives of England and the United States respectively, modeled a pairing pattern in which the guanine-cytosine, adenine-thymine interaction can be seen, which results in the double helix structure. of deoxyribonucleic acid.
Another thing that arises from the complementary nature of said pairing is the mechanism of transcription and replication, two fundamental processes for the processing and transfer of genetic information. This phenomenon can be both intramolecular and intermolecular; For example, the pairing of single-stranded RNAs takes place intramolecularly, between parts of a single strand that complement each other, while the bases of a DNA strand do so in the other way, intramolecularly, with those of the strand that complements each other. complements them.
The interactions that can be seen during base pairing are governed by hydrogen bonds. It is only possible to obtain stability if the pairs present an adequate degree of geometric correspondence . Over the decades since the first observation of base pairing, scientists have discovered several types; In addition to the already mentioned Watson and Crick , the Wobble , the Hoogsteen and the one that occurs with sugar oriented in trans or cis stand out.
In graph theory, finally, the pairing is the group of edges that lack shared vertices in a graph .
