Optical Tweezers (IMAGE) Michigan State University Caption The graphic represents two laser traps holding two beads (gray spheres), which are stretching out the DNA (gray spirals on both sides) holding the telomerase protein/RNA machine (center, colored purple protein) and teal RNA. The telomerase extends the DNA on the right (which represents the end of a chromosome) and the newly created DNA (yellow) forms a loop extruding from the machine.
