Option E is not true

Explanation:

All living cells are made up of genetic material (DNA). The DNA sequence in the same organism is same for all the cells of that organism. The difference in the cells is that the genes on the DNA sequence are not expressed at the same time. Some of the genes are silenced while others are expressed during gene regulation. This allows each cell to perform its specific function.

During the animal's development, the cell differentiates to produce the different kinds of cell the organism contains. This differentiation is as a result of expression and silencing of some genes on the same DNA sequence. Hence, different genes are expressed in the different cells which ultimately leads to production of different proteins.

But the DNA is the same across all cells in the organism.
