Polymerization


Definition:

  • (n.) The act or process of changing to a polymeric form; the condition resulting from such change.

Example Sentences:

  • (1) Natural tubulin polymerization leads to the formation of hooks on microtubular structures.
  • (2) The polymerization of dATP, dCTP, and dGTP onto the defined length initiator, d(pA)10, has been carried out in four buffers.
