Actin and Myosin

ID #1876

I seem to have two numbers by my actin filament diagram, 7nm and 50nm, is 7nm the diameter of an actin filament?

Yes, actin filaments are approximately 7 nm in diameter. That 50 nm measurement was just a scale bar on one of our figures, to give you a sense of scale like on a map where it says 1" = 1 mile or something like that.
