Transcript of Force Generation through Polymerization video

{Music}

How can a nanometer-scale protein generate and transmit forces to control cell shape changes across micrometer-scale distances? A crawling cell pushes its plasma membrane forward. The protein is actin. This is its story.

{Animation shows how cells make use of actin filament polymerization, how they branch and then crosslink to generate and transmit forces across long distances.}
