Resumen
Descripción
El artículo estudia el modo en que la genética actual emplea nociones provenientes de las ciencias y de las prácticas relativas al lenguaje oral o escrito para comprender la actividad de las biomoléculas: código, expresión, silenciación, edición son algunos de estos términos. Propone un itinerario que comienza con formulaciones generales que, desde el siglo XIX, aludían a un código biomolecular para culminar en la amalgama entre biología molecular y teoría tecnológica de la información desarrollada por el Dogma Central de la biología molecular en los años 1950. Luego, a partir del concepto de código genético, se analizan los modelos de comprensión aplicados por las propias ciencias del lenguaje a la genética: la lingüística molecular, la biosemiótica y la relación de ambas con los clásicos modelos comunicacionales de emisor-mensaje-receptor, al que alude directamente el Dogma Central, mostrando los límites de los diferentes modelos y su vínculo con algunos hallazgos experimentales recientes de la biología molecular. Finalmente, se sugiere que la teoría de los discursos sociales de E. Verón podría ser tomada como un nuevo modelo “bio-significante”. Se pretende con ello realizar un aporte al campo de las ciencias de la comunicación mediante la inclusión de ciertos aspectos de la biología molecular dentro de su égida

Then, based on the notion of genetic code, models of comprehension applied by the sciences of the language to the genetics were analyzed: molecular linguistics, biosemiotics and the relationship of both with the classic communication models of sender–message-receiver, mentioned directly by the Central Dogma, showing the limits of the different models and the link with some recent experimental discoveries of molecular biology. Finally, it is suggested that the theor y of the social discourses of E. Verón might be taken as a new "bio-significant" model. With this approach, it is expected to contribute to the field of the communication sciences by including certain aspects of the molecular biology under its aegis
