Aktinfilamente polar
WebIntermediate filaments are so named because they are thicker than actin filaments and thinner than microtubules or muscle myosin filaments. The subunits of intermediate filaments are elongated, not globular, and are associated in an antipolar manner. As a result, the overall filament has no polarity, and therefore no motor proteins move along … WebActin filaments assemble faster at the minus end than the plus end. False. Actin filaments assemble faster at the plus end. ... What are the two definitions or usages of the term polar in biology and chemistry? chemistry - separation of electrical charge biology - directionality, one end runs faster than the other ...
