However, it's important to note that:
* Not all genes are active in every cell. Different cell types express different genes, allowing them to specialize and perform specific functions.
* Cells can accumulate mutations over time. These mutations can alter the DNA sequence, though they are usually rare and do not significantly change the overall function of the cell.
So, while all human cells have the same DNA, they don't necessarily express the same genes and may have slight variations in their DNA sequence due to mutations.
