Detailed explanation-1: -Muscle cells are found specifically in muscles and possess the ability to shorten themselves due to the presence of motor proteins in them. Nerve cells are functional units of the nervous system. They are granular cells and help in the transmission of nerve impulses throughout the body.
Detailed explanation-2: -Although all cells contain the same DNA sequence, muscle cells are different from nerve cells and other types of cells because of the different genes that are turned on in these cells and the different RNAs and proteins produced.
Detailed explanation-3: -The correct answer is D. Muscle cells and nerve cells in one species of animal owe their differences in structure to differential gene expression. This is because these two cell types have exactly the same genes and the same types of ribosomes but they each express a different subset of these genes.
