Explanation:
Detailed explanation-1: -The striated appearance of skeletal muscle tissue is a result of repeating bands of the proteins actin and myosin that are present along the length of myofibrils . Dark A bands and light I bands repeat along myofibrils, and the alignment of myofibrils in the cell causes the entire cell to appear striated or banded.
Detailed explanation-2: -Skeletal muscles appear striated due to presence of two characteristic proteins in alternating dark and light bands.
Detailed explanation-3: -The dark staining region in the centre of the sarcomere is called the A (anisotropic) band.
