Detailed explanation-1: -Microfilaments. Of the three types of protein fibers in the cytoskeleton, microfilaments are the narrowest. They have a diameter of about 7 nm and are made up of many linked monomers of a protein called actin, combined in a structure that resembles a double helix.
Detailed explanation-2: -In microfilaments, however, which are also often referred to as actin filaments, long polymerized chains of the molecules are intertwined in a helix, creating a filamentous form of the protein (F-actin).
Detailed explanation-3: -Microfilaments assist with cell movement and are made of a protein called actin. Actin works with another protein called myosin to produce muscle movements, cell division, and cytoplasmic streaming. Microfilaments keep organelles in place within the cell.
Detailed explanation-4: -Microfilaments are unbranched solid rods made up of actin proteins in association with myosin protein.
Detailed explanation-5: -There are generally two types based on structure: bundles and networks. Microfilament bundles are long microfilaments that may associate with contractile proteins (e.g. non-muscular myosin). These microfilaments are involved in moving substances within the cell.
