Now, the flagella inside Eukaryotes is made of this tubulin. But inside Prokaryotes, our flagella is not made from tubulin, so it's not made from microtubules. It's made from a different type of protein known as flagellin. And we're going to discuss the difference between the flagellin, Cypriots and Eukaryotes in a different lecture. So don't worry about that just yet. So now that we discuss the three different types of fibers that are found within the cytoskeleton of the eukaryotic cell, let's basically summarize our findings.
