Cells on the move reach forward with lamellipodia and filopodia, cytoplasmic sheets and rods supported by branched networks or tight bundles of actin filaments.
Few molecules are more interesting than DNA—except of course RNA. After two decades of research, that "other macromolecule" is no longer considered a mere messenger between glamorous DNA and protein-synthesizing machines.
In a standard biology textbook, cells tend to look more or less the same from all sides.
