DNA stands fordeoxyribonucleic acid. It’s the genetic code that determines all the characteristics of a living thing.Basically, your DNA is what makes you, you!
You got your DNA from your parents, we call it ‘hereditary material’ (information that is passed on to the next generation). Nobody else in the world will have DNA the same as you, unless you have an identical twin.
Deoxyribonucleic acid is a large molecule in the shape of a double helix. That’s a bit like a ladder that’s been twisted many times. DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code Hope you understood it.
