Explanation:
Detailed explanation-1: -These cells are different because they use the same set of genes differently. So even though each of our cells has the same 20, 000 or so genes, each cell can select which ones it wants to “turn on” and which ones it wants to keep “turned off".
Detailed explanation-2: -Your liver cells, brain cells, and the cells lining your stomach all contain the same genes.
