Dynein - Study guides, Class notes & Summaries

The most common isotope of carbon contains a nucleus with 6 protons and 6 neutrons. Suppose you have a beaker containing 6 grams of pure carbon. Approximately how many moles of carbon are present in the beaker? Eukaryotic cells move when their flagella or cilia bend. How does the bending of these structures occur? A) The Golgi apparatus transports numerous vesicles to these structures, making them bulge. B) Actin filaments are bound by the motor protein myosin. C) The motor protein dynein chan...
