The organization and quantity of myosin irrigation into myosin-free “ghost” fibers were compared between normal and PSE myosin. Considerable amounts of myosin were incorporated into the “ghost” fibers for both normal and PSE myosin. Elec t ron microscopic s tudy showed tha t the myosin f i laments were formed a l l over the thin filaments after the irrigation. However, there was almost no diffe...

Over 30 years ago, Melvin Conway proposed what has since become known as Conway’s Law—that the structure of the system mirrors the structure of the organization that designed it.1 This rel...
