DNA stands for DeoxyriboNucleic Acid.
DNA is found in every living thing.
DNA is inherited from our parents.
The structure of DNA is a double helix, so it looks like a spiral staircase.
DNA consists of bases, sugars, and phosphates.
The bases in DNA are adenine (A), guanine (G), thymine (T), and cytosine (C).
The bases exclusively pair as A to T and
C to G.
DNA is found in genes contained in chromosomes.
46 chromosomes are found in humans.
The number of chromosomes can vary from species to species.
The combination of bases is unique for every person except identical twins.
Identical twins have identical DNA profiles.
Children inherit half of their DNA from their mothers and half from their fathers.
Because DNA is unique for each person, it can be used to identify people.
