Due to single nucleotide polymorphisms (SNPs), all humans have a slightly different nucleotide sequence for their genome. Restriction mapping is used in forensic sciences to match DNA evidence to a potential suspect of a crime. How does restriction

mapping reduce the likelihood of misidentifying a suspect?

A) SNPs add and remove restriction sites resulting in a unique "fingerprint" for each person
B) SNPs only remove restriction sites from the genome resulting in a unique "fingerprint" for each person
C) SNPs change the genes that are expressed
D) SNPs only add new restriction sites to the genome resulting in a unique "fingerprint" for each person
