ADN Transporte electrónico Corriente eléctrica Transmitancia. DNA have presented through experiments great variability in terms of its electronic characteristics. They have shown that it can acquire the behavior of a conductor, semiconductor or insulator, making it a good candidate for replicating at the mesoscopic scale electronic devices. In the present work, the quantum transmission coefficient is calculated for DNA chains of various lengths with the use of the decimation and renormalization procedure, within the tight binding approximation and the Lippmann-Schwinger scattering theory. Transmission-Energy profiles were obtained, which helped to infer electronic transport properties of the system, Additionally, the current-voltage relation for a 30-pairs chain was calculated as well, and compared with the experimental results of Porath et al. Results show the semiconductor characteristics of the molecule, and a resemblance with the work of Porath, showing the quality of the procedure and the model utilized. El ADN ha presentado a través de experimentos una gran variabilidad en términos de sus características electrónicas. Han demostrado que puede adquirir el comportamiento de un conductor, semiconductor o aislante, lo que lo convierte en un buen candidato para replicar en dispositivos electrónicos a escala mesoscópica. En el presente trabajo, el coeficiente de transmisión cuántica se calcula para cadenas de ADN de varias longitudes con el uso del procedimiento de diezmado y renormalización, dentro de la aproximación de unión estrecha y la teoría de dispersión de Lippmann-Schwinger. Se obtuvieron perfiles de transmisión de energía, lo que ayudó a inferir las propiedades de transporte electrónico del sistema. Además, también se calculó la relación corriente-voltaje para una cadena de 30 pares, y se comparó con los resultados experimentales de Porath et al. Los resultados muestran las características de los semiconductores de la molécula, y un parecido con el trabajo de Porath, mostrando la calidad del procedimiento y el modelo utilizado.
