nucleation


nucleation
A general term used in polymerization or assembly reactions where the first steps are energetically less favoured than the continuation of growth. Polymerization is much faster if a pre-formed seed is used to nucleate growth. (eg. microtubule growth is nucleated from the microtubule organizing centre, although the nature of this nucleation is not known).
