The cytoskeleton of a cell is made up of microtubules, actin filaments, and intermediate filaments. These structures give the cell its shape and help organize the cell's parts. In addition, they provide a basis for movement and cell division.ll cytoskeletons consist of three major classes of elements that differ in size and in protein composition. Microtubules are the largest type of filament, with a diameter of about 25 nanometers (nm), and they are composed of a protein called tubulin.
In DNA, cytosine (C) is always bonded (i.e. attached) to guanine (G), and thymine (T) is always bonded to adenine (A). This is the general rule. But there are many different types of bonds, namely: single bonds, double bonds, and triple bonds. Just imagine the molecules holding hands.
