Genetic accelerators reveal themselves


The DNA of two people differs in millions of places. But which of those variants also have an actual effect on how our bodies function? Researchers from the Netherlands Cancer Institute have developed a technique that allows them to see which changes in the genetic code affect the activity of genes and, therefore, how we function. They publish their findings in the Nature Geneticsjournal on June 28th. "We can now learn a lot more from all those genomes that are currently being sequenced."

It is becoming easier and cheaper to read the code from human DNA. In that code, we can see, for example, that the DNA of two people differs from each other in as many as 4 million places. But what can we actually do with that information? Small DNA changes do not always have an effect on the functioning of cells, and therefore on us.
