They actually have different DNA in the two types of cells.

|
The genome of the different cells changes
|
Detailed explanation-1: -Gene regulation is how a cell controls which genes, out of the many genes in its genome, are “turned on” (expressed). Thanks to gene regulation, each cell type in your body has a different set of active genes – despite the fact that almost all the cells of your body contain the exact same DNA.
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: -There are around 200 specialized cell types in the human body, each type with a specific function. However, every cell in an organism contains the same DNA. How is this possible? Because different genes are expressed in different cell types, different proteins are made and cells become specialized.
