IN THE PINC Valentis' PINC polymers, such as polyvinyl-pyrrolidone, interact with DNA without condensing it. The white and red shading depicts hydophobic and hydrophilic regions of the polymer. The white is the most hydrophobic and thus indicates that the polyvinyl backbone (hydrophobic) is coating the DNA and rendering its surface more hydrophobic.
