What is the role of the gamma-tubulin ring complex (γ-TuRC)?
Show answer and explanation
Correct answer: It templates microtubule nucleation at the centrosome
The gamma-tubulin ring complex (gamma-TuRC) is concentrated at the centrosome and serves as the nucleation template from which alpha/beta-tubulin dimers begin to polymerize. It defines the minus end of nascent microtubules and ensures they grow outward toward the cell periphery.
