How is it that cells of the body are able to differentiate? each cell has the same set of dna but once the cell differentiates, it loses the dna that is not needed each cell contains only the dna needed to it with its function each cell contains the same set of dna but different genes are turned off or on depending on the cell's function each cell contains a different set of dna

Each cell contains the same set of DNA but different genes are turned off or on depending on the cell's function.

Explanation:

Every cell contains the same amount and same DNA in the nucleus, the only difference in differentiated cells is that DNA not relevant to the cell's function are silenced and hence not expressed. As the cell therefore only expresses genes to perform a specific function, it is said to be differentiated and specialised for that particular function. Note that the earlier answer given is incorrect.

well the answer is 2!
