Identical Twins Reveal Mechanisms Behind Aging, Uppsala Universitet Study
2/3/2012 7:03:34 AM
In a recent study led by Uppsala University, the researchers compared the DNA of identical (monozygotic) twins of different age. They could show that structural modifications of the DNA, where large or small DNA segments change direction, are duplicated or completely lost are more common in older people. The results may in part explain why the immune system is impaired with age.
