Every human being shares 99.9% of their DNA with every other human. 1 . If you put all the DNA molecules in your body end to end, the DNA would reach from the Earth to the Sun and back over 600 times (100 trillion times six feet divided by 92 million miles).
What happens to DNA when it is damaged?
DNA is a fragile molecule. About a thousand times a day, something happens to it to cause errors. This could include errors during transcription, damage from ultraviolet light, or any of a host of other activities. There are many repair mechanisms, but some damage isn't repaired. This means you carry mutations! Some of the mutations cause no harm, a few are helpful, while others can cause diseases, such as cancer. A new technology called CRISPR could allow us to edit genomes, which might lead us to the cure of such mutations as cancer, Alzheimer's and, theoretically, any disease with a genetic component.
