===SNP===

Single nucleotide polymorphism (SNP) is a genetic variation
among human beings. Each SNP represents a difference in a nucleotide which is
a single DNA molecule. For instance, one SNP may replace a nucleotide of base
guanine (G) with cytosine (C). These SNPs can be found nearly once in every 1,000
nucleotides on average in a person's DNA. Most SNPs do not effect health of owner.
However, some of these variations may associate with diseases.
