What is a SNP

SNP is also called a Single Nucleotide Polymorphism. Your DNA consists of 4 main building blocks (nucleotides), Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). In certain locations within your DNA, one person may have an A, whereas another may have a G. This difference in the base pair is often called a variant. This variant is an SNP.
