It is shown that in a Holstein molecular chain placed in a stronglongitudinal electric field some new types of excitations can arise. Thisexcitations can transfer a charge over large distance (more than 1000nucleotide pairs) along the chain retaining approximately their shapes.Excitations are formed only when a strong electric field either exists orquickly arises under especially preassigned conditions. These excitationstransfer a charge even in the case when Holstein polarons are practicallyimmobile. The results obtained are applied to synthetic homogeneous PolyG/PolyCDNA duplexes. They can be also provide the basis for explanation of famous H.W.Fink and C. Sch\"{o}nenberger experiment on long-range charge transfer in DNA.
