Respuesta :
It exists in virtually every cell of the human body and differs in its sequence of nucleotides.
DNA fingerprinting usually involves introns because exons are much more.
and the likelihood that they would be in close proximity, but it also became
used.
Shorter repetitive sequences, or short tandem repeats (STR), were later

They are in almost every human cell and its sequence of nucleotides is different in each one of the them. The DNA fingerprint includes intron because exon are more conserved so they have less variability in their sequence.
The orginal answer is on encyclopedia, I change the wording in order to advoid plagerism. I hope I helped :)
