Question 2: A fourth eukaryotic cytoskeletal element, microtrabeculae, was proposed by Keith Porter based on images obtained from high-voltage ________ of whole cells in the 1970s.
Question 3: The cytoskeleton was previously thought to be a feature only of ________ cells, but homologues to all the major proteins of the eukaryotic cytoskeleton have recently been found in prokaryotes.
Question 5: Filaments of ParM exhibit dynamic instability, and may partition plasmid DNA into the dividing daughter cells by a mechanism analogous to that used by microtubules during eukaryotic ________.
Question 7: During cell division, FtsZ is the first protein to move to the division site, and is essential for recruiting other proteins that synthesize the new ________ between the dividing cells.
Question 8: The cytoskeleton provides the cell with structure and shape, and by excludingmacromolecules from some of the ________ it adds to the level of macromolecular crowding in this compartment.
