DNA finger print

The Chemical structure of everyone,s DNA is same.
The chemical structure of man and animals are also the same.
The Different between animals and within people is also generated by DNA, So how it happens if DNA structure is same...
That happens like this
although the chemical structure of a DNA is same order of the base pairs of DNA is different. This will occur the differences between animals.
every person has different sequence of DNA to identify a person scientists have to recognize this sequence of millions of DNAs so scientists use short method to do that because of repeating pasterns in DNA
This method will not able to recognize people separately but will able to recognize whether the two DNA samples are from same person.
