New Quad stranded DNA found

The typical DNA structure is the two-stranded spiraling helix structure. But researchers of Imperial College London (Chemistry department) have found a quadruple-helix form of DNA. This odd four-stranded DNA can play a role in cancer-causing.

For instance, drugs could stop this odd DNA from contributing to cancerous tumor growth. The team described that certain protons can cause G-quadruplex to disentangle. In the future, this work would lead to a new dimension of treatment that would disrupt the activity of quadruple helix DNA.
