详细研究了合成和基因组DNA序列的电荷传输特性。在这项工作中考虑了人类和侏儒黑猩猩的22号染色体、λ-噬菌体和D1 s80基因的基因组序列，并与核苷酸的周期性和准周期性（斐波那契）序列进行了比较。电荷转移效率进行了比较，所有这些不同的序列，和电荷转移效率的大的变化，源于序列依赖性的影响，报告。此外，隧道电流的基本特性，包括接触效应，进行了说明。最后，给出了不同温度下金属间碱基的热电势。
A detailed study of charge transport properties of synthetic and genomic DNA sequences is reported. Genomic sequences of the Chromosome 22, λ-bacteriophage, and D1s80 genes of Human and Pygmy chimpanzee are considered in this work, and compared with both periodic and quasiperiodic (Fibonacci) sequences of nucleotides. Charge transfer efficiency is compared for all these different sequences, and large variations in charge transfer efficiency, stemming from sequence-dependent effects, are reported. In addition, basic characteristics of tunneling currents, including contact effects, are described. Finally, the thermoelectric power of nucleobases connected in between metallic contacts at different temperatures is presented.
