Accepted Answer. The Dragon Scale can be found on wild Horsea, Seadra, Dratini, and Dragonair. The only hitch to your plan is that you can only find them after getting the National Dex and Dratini and Dragonair can only be found by using the Super Rod, behind the Waterfall, at Mt. Coronet.
Microtubules are conveyer belts inside the cells. They move vesicles, granules, organelles like mitochondria, and chromosomes via special attachment proteins. They also serve a cytoskeletal role. Structurally, they are linear polymers of tubulin which is a globular protein.
ofmicrotubules. They are long, thin, and stringy proteins (mainly actin) compared to the rounder, tube-shaped microtubules. We'd like to say you can find them here or there, but they are everywhere in a cell. They work with microtubules to form the structure that allows a cell to hold its shape, move itself, and move its organelles.
