What Is DNA?
Present in almost every cell of your body, Deoxyribonucleic Acid, known as DNA, is your unique genetic blueprint. Your DNA determines the structure and function of every component in your body, such as eye and hair color, height, and susceptibility to disease. With the exception of identical twins, everyone’s DNA is unique.
DNA is the genetic blueprint found in every living cell. A DNA sample smaller than a grain of sand can accurately establish and verify any dogs: A. Identity. Every dog has a unique genetic pattern. This is what we call the DNA Profile. Once a dog has been profiled, this evidence of its identity can never be changed. Your dogs DNA profile is absolutely unchangeable. B. Parentage. Each dog inherits his genetic profile from his parents and cannot have any pattern that is not inherited from his Sire or his Dam. Genes come in pairs with each parent contributing one of the genes in each pair.
DNA is the chemical compound which genes are made of and is often referred to as the building blocks of life. Your genes are inherited from both your parents and contains the information that distinguishes who you are. Genes tell us: • whether we are male or female • the colour of our hair and skin • which diseases we are at risk of developing For more simple explanations on what DNA and genes are, you can check out the following links: Wikipedia – Definition of DNA CSIRO’s Double Helix Science Club GlaxoSmithKline’s Kids Genetics on Genes – for the interactive demo, click on the “More on Genes” icon.

Deoxyribonucleic acid (DNA) is a chemical substance found in most cells of the human body (and in most cells of all living organisms). The DNA in an individual\’s blood is the same as the DNA found in their hair roots and skin cells. DNA stores information that is needed for passing down our genetic characteristics from one generation to the next for example, what we look like and how we develop hence it is also known as our genetic blueprint. Half of each person\’s DNA comes from their mother and the other half from their father.
