This short paper explores intriguing analogies between helical structures of electron and elementary particles and circular supercoiled DNA. I propose a strong relation between the dispositions Lk=Tw+Wr (Lk=const., changing Twist and Writhe) and the quark compositions Q=I3+Y/2 (examples: Q=const., varying Isospin an Hypercharge; or Strangeness S or Y=const. varying Charge and Isospin).
