Today is National DNA day! Let’s learn some fun facts about DNA
What is DNA? DNA stands for Deoxyribonucleic acid, a molecule containing genetic instructions that ensure living beings can properly develop, survive, and reproduce, with every human being inheriting half of their genetic material from each of their biological parents. DNA can be found in almost every cell in our body, except for red blood cells, making it an essential component in what makes us human.
1. All human beings share approximately 99.9% of their DNA
The tiny amount of DNA that differs (0.1%) is what makes us different from one another. This area of our DNA is responsible for determining our physical characteristics like eye colour, skull shape and skin colour.
2. It would take 50 years to type out the entire human genome
There are around three billion units that make up the human genome. It would take around 50 years to type out the entire genome – but you’d need to type at 60 words per minute, for eight hours per day.
3. DNA is made up of four key building blocks
DNA molecules are made up of four chemical bases (nucleotides), which are the building blocks of nucleic acids: adenine (A), guanine (G), thymine (T), and cytosine (C).
4. If you stretched out the DNA in one cell, it would stretch to 2 metres long
If you did this for all the DNA in all your cells, it would stretch to approximately twice the diameter of the solar system!
5. It’s possible for one person to have two sets of DNA
Although rare, it’s possible for a human being to have two completely different DNA profiles. This phenomenon is known as chimerism and can happen during pregnancy where the mother retains some of her baby’s DNA, or when a fetus absorbs its twin. It can also occur in patients who’ve had bone marrow transplants, where the donor’s bone marrow continues to produce blood cells containing the donor’s DNA.
