Abstract

We presented the results of a study of the electrical resistance of two types of short single-stranded DNA molecules consisting of only one type of nucleotides — dA or dC, using scanning tunneling microscopy and spectroscopy. It was found that the resistance of dC12 homooligonucleotides is slightly higher than that of dA12 homooligonucleotides.
