Answer:

Almost every cell? in our body contains our DNA?.

On average, about 99.9 per cent of the DNA between two humans is the same.

The remaining percentage is what makes us unique (unless you are an identical twin!).

Although this might sound like a small amount, it means that there are around three million base pairs? that are different between two people. These differences can be compared and used to help distinguish you from someone else.  

Minisatellites are short sequences (10-60 base pairs long) of repetitive DNA that show greater variation? from one person to the next than other parts of the genome?. This variation is exhibited in the number of repeated units or ‘stutters’ in the minisatellite sequence.
