"Quadruple helix" ( 4-strand ) DNA found by scientists

As an avid observer and participant in that DNA "thing", I was pleasantly surprised to see this on Thwatter :
'Quadruple helix' DNA seen in human cells
<snip>
Cambridge University scientists say they have seen four-stranded DNA at work in human cells for the first time.

The famous "molecule of life", which carries our genetic code, is more familiar to us as a double helix.

But researchers tell the journal Nature Chemistry that the "quadruple helix" is also present in our cells, and often in functions related to cancer.

They suggest that control of the structures could provide novel ways to fight the disease.

Enjoy the ride ;)
