Scientists have shown that in one in every 4,000 births, some of the genetic code from our mitochondria — the ‘batteries’ that power our cells — inserts itself into our DNA, revealing a surprising new insight into how humans evolve. Researchers show that mitochondrial DNA also appears in some cancer DNA, suggesting that it acts as a sticking plaster to try and repair damage to our genetic code.
