How dome some cells become brain cells and others become skin cells, when the DNA in all the cells is exactly the same. In other words, if the instruction are exactly the same, how does one cell become a brain cell and another a skin cell?

All multicellular organisms develop from a single fertilized egg cell known as a zygote. As this cell divides by mitosis, each new cell that is formed contains the exact same genetic material. As the organism develop certain genes in certain cells are activated and others are inactivated so that cells develop into specialized cells such as brain cells and skin cells.

Some cells become brain cells and others become skin cells, when the DNA in all the cells is exactly the same due to a process called cell differentiation.

What is cell differentiation?

Cell differentiation is the process whereby dividing cells change their functional or phenotypical type i.e. they become specialized in their function.

The cells of every living organism contains the exact DNA, however, they are not expressed the same way.

The difference in the way genes are expressed leads to the process of cell differentiation.

Therefore, some cells become brain cells and others become skin cells, when the DNA in all the cells is exactly the same due to a process called cell differentiation.
