Identify the structural makeup of actin filaments, intermediate
filaments, and microtubules
Step by step
Solved in 2 steps
- In cells, actin filaments form bundles or networks. How do cells form such structures, and what specifically determines whether actin filaments will form a bundle or a network?Actin filaments, microtubules, and bacterial flagella are all built from small subunits. Describe three advantages of assembling long filamentous structures from subunits rather than from single, long proteins.How is filament polarity detectable?
- Microtubules are polar filaments; that is, one end is different from the other. What is the basis for this polarity, how is polarity related to microtubule organization within the cell, and how is polarity related to the intracellular movements powered by microtubule-dependent motors?Define what is intermediate filament ?If the graph represents one actin filament, and line A represents dynamic activity at the plus end and line B represents dynamic activity at the minus end, which of the following must be true? Group of answer choices Formin proteins have been removed. Treadmilling is occurring at 1000 mM. CapZ proteins are not present. Nucleation is occurring at 100 mM.
