nucleation
nucleˈation [f. nucleate v.] a. The formation of nuclei, esp. by the aggregation of molecules into a new phase within a medium. b. The formation of something, esp. a crystal, droplet, or bubble, on or into a nucleus.1861 H. Macmillan Footn. fr. Nature 243 Giving rise either by gemmation or nucleatio... Oxford English Dictionary

Microtubule nucleation
Branching MT nucleation Studies using Xenopus egg extracts have identified a novel form of microtubule nucleation that generates fan-like branching arrays In the branching nucleation described above, the addition of TPX2 to the egg extracts led to a dramatic increase in nucleation events—while in other studies wikipedia.org

What is meant by nucleated in this context? Hi I am little confused in one of my classes; because the teacher will say that " the actin is nucleated by the ARP 2/3 complex" or "microtubles are nucleated by the centros...

What does it mean to "nucleate multi-protein complexes"? I am reading an article about the mTOR signalling pathway and I have come across the following: > mTOR nucleates at least two distinct multi-protein complexes,...
Here nucleation has a rather physical meaning. mTOR acts as the starting assembly point of the complex.

Classical nucleation theory
Homogeneous nucleation Homogeneous nucleation is much rarer than heterogeneous nucleation. This is because the nucleation barrier for heterogeneous nucleation is much lower than for homogeneous nucleation. wikipedia.org

你知道哪些「高冷」的知识？
超纯水的这种冻结也被称为均质成核（homogeneous nucleation）。与之相对的是，自然界中的水很难保持真正纯净，其中所含杂质可以成为冰晶生长的起点，也就是结晶核。 这就如同某些抽奖系统事先已经安排好了中奖号码，让某些人可以占尽先机。 结冰也就因而成为一个大概率事件。 因为是由其他物质充当结晶核，所以这被称为异质成核（heterogeneous nucleation）。 这也就解释了，河流湖泊结冰时，为何总是先从水面开始，因为在这种界面交互的地方，气泡和灰尘都可以提供更加良好的成核位置，让结晶顺利成长。 zhihu
