Helical vs. Random Coil Polymers as Gene Delivery Agents

Caption: Polymers as gene delivery agents. Helical charged polypeptides, left, deliver DNA to the cell by rupturing the endosomal membrane. Random-coil polymers, right, do not rupture the membrane, so the DNA is not released inside the cell.
