On the basis of Szent‐Györgyi's recent suggestion that electron acceptors transform proteins from insulators to conductors, the possibility of charge transfer between proteins and electron acceptors and/or donors is discussed. Some problems arising in connection with the determination of the amount of charge transferred are mentioned. Afterwards possible methods to determine the correct positions and widths of partially filled bands in polymers are reviewed. Following this, the problem of interactions between charged polymers with partially filled bands is discussed. Finally the possible role of charge transfer in regulating the available (readable) part of the genetic information is pointed out.
