DNA molecules possess high density genetic information in living beings, as well as self-assembly and self-recognition properties that make them excellent candidates for many scientific areas, from medicine to nanotechnology. The process of electron transport through DNA is important because DNA repair occurs spontaneously via the process that restores mismatches and lesions, and furthermore, DNA-based molecular electronics in nano-bioelectronics can be possible through the process. Our work considers a one-dimensional one-channel DNA model, a quasi-one-dimensional one-channel DNA model, and...
