Muscle cells produce myofibrillar proteins, such as actin and myosin, which are important to the muscle fiber structure and function.
Bone cells do not produce these proteins.
Why does this specialization occur?
O Different genes are active in muscle cells than are active in bone cells.
O Muscle cells contain recombinant DNA, while bone cells do not.
O Muscle cells contain a nucleus with DNA, while bone cells do not.
O The genes in muscle cells are totally different from those in bone cells.
