| nucleation | <molecular biology> 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). (18 Nov 1997) |

| ice nucleation protein | <protein> Protein produced by some gram-negative bacteria that promote the nucleation of ice, apparently by aligning water molecules along repeated domains of 48 amino acids, that consist of 16 residue repeats containing the conserved octamer AGYGSTxT. Now finding commercial use in snow making at ski resorts. (18 Nov 1997) |

| nucleation |
1) (homogeneous) the initiation of solid crystals from the liquid stage, or initiation of solid crystals from the liquid stage, or a new phase within a solid without outside interference - rarely occurs, 2) heterogeneous) foreign particles altering the liquid-solid interface energy during phase changes.

| nucleation |
Also called grafting or implementation, the process of inserting an irritatant (nucleus) into the body of a mollusk so that it will secrete nacre to cover it, consequently producing a cultured pearl.

| nucleation |
Also termed grafting or implantation. Process of inserting a hard bead nucleus or piece of soft mantle tissue into a mollusc body or mantle of the mollusc.The nucleus or mantle tissue serves as the 'seed' to irritate the mollusc to produce a pearl.
