Detailed explanation-1: -Your muscle cells and nerve cells have the same DNA but work differently. A nerve cell transports information to other cells in your body. A muscle cell has a structure that aids in your body’s ability to move.
Detailed explanation-2: -The DNA of a skin sell and a muscle cell are identical. But the skin cell may contain the proteins collagen and keratin in high amount, which the muscle lacks (or has very little of), while the muscle cell may have large amounts of the proteins actin and myosin, which the skin cell lacks (or has very little of).
Detailed explanation-3: -Human nerve cells differ from human muscle cells because different sets of genes are expressed; in each type of cell, different genes are transcribed into mRNA and translated into protein.
