DNA - What Is It?
DNA - short for Deoxyribonucleic Acid - is the blueprint of life. It
carries genetic information passed on to you from your mother and
father and determines your physical characteristics. DNA analysis
is rapidly becoming the "genetic fingerprint" of the new millennium.
the most simple terms, DNA is the fundamental building block that
defines each of us as individuals. Every cell of every living entity
contains DNA that is unique to that animal or plant. Each person's DNA is
exactly the same in every one of their cells and nobody else's DNA is
exactly the same. A DNA sample is a sample of cells from a person's body.
The type of sample required is a bucal swab (a mouth swab)
usually taken with a cotton swab or bud.
