When a skeletal muscle relaxes,myosin head attach to actin by breaking down ATP to ADP and phosphate with the help of myosin ATPase. The myosin head forms the cross -bridges on the active site of the actin.The cross-bridge pulls the actin which slide over the myosin. The release of ADP completes the cross-bridge movements . ATP attaches to myosin, and break the actin -myosin cross-bridge. Thus breaking of ATP into ADP and phosphate help the thin filament to return to their original position.
Answer:
Recombinant DNA technology or genetic engineering.
Explanation:
Genetic engineering is a process that uses some techniques to cut and join DNA from biological species and introducing the novel DNA into another organism in order to form new combinations of traits or characters that can be inherited.
