of the three types of fibers; microfilaments (or and intermediate filaments are fibers with diameters in a Microtubules are the filaments) are the middle range. Microtubules are hollow rods about 25 nm in diameter and 200 nm to 25 um in length. Microtubule fibers are constructed of the globular protein A tubulin dimer consists of two slightly different polypeptides: a-tubulin and B-tubulin. Microtubules shape and support the cell and serve as tracks to guide motor proteins carrving organelles to their...

Please thoroughly explain why each of the answers in correct or incorrect. Which of the following statements about the cytoskeleton is incorrect? A. The dynamic aspect of cytoskeletal function is made possible by the assembly and disassembly of a few simple types of proteins into large aggregates. B. Microfilaments are structurally rigid and resist compression, while microtubules resist tension (stretching). C. Movement of cilia and flagella is the result of motor proteins causing microtubules to move relative to each other...

Which of the following statements are true? Select one or more: a. Two sister chromatides arise by replication of the DNA of the same chromosome and remain paired as they line up on the metaphase plate b. Microtubule polymerization and depolymerization and microtubule motor proteins are all required for DNA replication during 5 Phase X C. Centrosomes are duplicated before M Phase begins d. Microtubules nucleate at the centromeres and then connect to the kinetochores, which are structures at the...

Please HELP with these two
questions and explain your reasoning
Confirm your knowledge: What makes transport of NES-tagged proteins directional? (out of the nucleus only) A) Exportin binds Ran-GTP in the cytoplasm, stops Exportin from re-binding NES. B) Ran-GTP is created in the nucleus, and NES cannot bind Exportin without it. C) The NES is cleaved off, so exported protein cannot re-bind Exportin. Apply your reasoning: What is the area called that is indicated by the arrow? (See diagram.) A)...
