This means that the nuclei in your brain cells contain the same DNA as the nuclei in your liver cells. The reason they don't 'act' the same is because not all cells use every single gene contained in the DNA. Genes can be activated ("turned on") or deactivated ("turned off") by environmental influences like; hormones, temperature, light and chemical pollutants.
