Researchers examined human bone marrow cells from 19 people of different genders and ages. They found that 84 percent of the participants had significant deviations from the standard DNA code. These deviations included missing pieces of chromosomes, for example.

Even when we are young, our cells are apparently more different than previously thought. The study also shows that our cells differ more from each other than there are differences between people. They found the changes in completely healthy people. The current opinion, however, is that every cell in our body has exactly the same DNA.
