The DNA is different, but each cell contains the same genes

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: -Your amazing body contains hundreds of different cell types, from immune cells to skin cells to neurons. Almost all of your cells contain the same set of DNA instructions – so why do they look so different, and do such different jobs? The answer: different gene regulation!
Detailed explanation-3: -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.
