The all‐valence electron (CNDO/2 and MINDO/2) band structures of the homopolynucleotides are compared with those of the sugar‐phosphate backbone of DNA. It is concluded that the possibility of a charge transfer reaction from the valence band of the poly (base pairs) (coming from the highest filled guanine level) to the low‐lying rather broad conduction band of the strictly periodic sugar‐phosphate chain cannot be excluded. The consequences of this assumed charge transfer reaction on the conduction properties of DNA are discussed.
