Quick Glimpse Behind the Science
Every cell in our bodies – from heart to skin, blood to bone – contains a complete set of our DNA.

Genetically we are almost identical, but in each gene there are points of variation. The most common type of variation is a single base change at a particular position – this variation is called a Single Nucleotide Polymorphism, or SNP for short (pronounced ‘snip’).
