Human brains cells have- 1. contain only the parts of dna that are needed
2. the same dna molecules as the other cells but some parts of the dna are turned on and other parts off.
3. half the dna molecules as liver cells and use different parts of the dna to preform different specialized functions
4. a different number of dna molecules as other cells​
