A new form of DNA has been discovered inside living human cells for the first time. 

Named i-motif, the form looks like a twisted ‘knot’ of DNA rather than the well-known double helix.

It is unclear what the function of the i-motif is, but experts believe it could be for ‘reading’ DNA sequences and converting them into useful substances.

The discovery was made by scientists from the Garvan Institute of Medical Research in Sydney.

Although researchers have seen the i-motif before, it has only been witnessed under artificial conditions in the laboratory, and not inside cells.

Scientists have previously debated whether i-motif ‘knots’ would exist at all inside living things – a question that is resolved by the new findings, published in Nature Chemistry.
