The _______ link is an elastic protein-based linkage that connects tubulin doublets in cilia and flagella. The resultant bridges play an important role in ciliary and flagellar movement by limiting the extent that adjacent doublets can slide over one another. The resistance to sliding provided by these bridges causes the axoneme to bend.
A)plectin
B)filamentin
C)nexin
D)vimentin
E)myosin

Question

Quizplus · Accepted Answer

The elastic protein-based linkage that connects tubulin doublets in cilia and flagella is called the nexin link. The nexin links provide resistance to sliding, which causes the axoneme to bend. Plectin, filamentin, vimentin, and myosin are not involved in this process.
