Question

1. in eukaryotic flagella, the fibers that slide past one another due to the activity of dynein proteins are
2. many cell organelles, most notably the nucleus, are anchored by which are assembled from a diverse class of proteins.
3. centrosomes are sites where protein dimers assemble into
4. the extension of pseudopodia in amoeba is due to the regulated assembly and destruction of
5. the only cytoskeletal fibers not associated with intracellular movement or whole cell locomotion are the
6. during muscle contractions, myosin motor proteins move across tracks of

Explanation:

1. Microtubules are the fibers in eukaryotic flagella that slide due to dynein activity.
2. Intermediate filaments anchor cell - organelles like the nucleus.
3. Microtubules assemble from protein dimers at centrosomes.
4. Microfilaments are involved in pseudopodia extension in amoeba.
5. Intermediate filaments are not associated with intracellular movement or whole - cell locomotion.
6. During muscle contractions, myosin moves across microfilament tracks.
