Noun
a chemical process that combines several monomers to form a polymer or polymeric compound
Source: WordNetThere appear to be mechanisms by which an external chemotactic gradient is sensed and turned into an intracellular PIP3 gradient, which results in a gradient and the activation of a signaling pathway, culminating in the polymerisation of actin filaments. Source: Internet
The polymerisation is also temperature-dependant: storage at zero degrees or below stops it, so keeping it in the freezer is also effective. Source: Internet
This motor activity, coupled with polymerisation and depolymerisation of microtubules, provides the pulling force necessary to later separate the chromosome's two chromatids. Source: Internet
