Definition of Nucleation

1. [n -S]

Medical Definition of Nucleation

1. A general term used in polymerisation or assembly reactions where the first steps are energetically less favoured than the continuation of growth. Polymerisation is much faster if a pre formed seed is used to nucleate growth. (e.g. Microtubule growth is nucleated from the microtubule organising centre, although the nature of this nucleation is not known).
