Frog skeletal muscle contains thick filaments that are 3.0um long and thin filaments 2.0 um long. If the uncontracted sarcomere is 4.4 um long, and the contracted sarcomere is 3.4 um long, what is the length of the A bands in micrometers and I bands before contraction? And after contraction what is the size of the A band and I bands in micrometers? Your answer should be a number with one figure after a decimal point like 1.0 or 1.1 as examples.
