The eukaryotic cytoskeleton is a highly dynamic network of filaments and motor proteins. Which of the following correctly describe activities of these cytoskeletal components? The eukaryotic cytoskeleton is a highly dynamic network of filaments and motor proteins. Which of the following correctly describe activities of these cytoskeletal components? Nuclear lamins are organized into long parallel bundles that help stiffen the cell and define its shape. Myosin motors walk toward the plus ends of intermediate filaments. Actin filaments are required for cytoplasmic streaming. Kinesin motors are responsible for the whiplike movement of eukaryotic flagella.
