In a world first, researchers have identified a new DNA structure -- called the i-motif -- inside cells. A twisted 'knot' of DNA, the i-motif has never before been directly seen inside living cells.

For the first time, scientists have detected a DNA structure inside living human cells that looks more like a four-stranded knot than the elegant double helix we learned about in school.

Scientists have discovered a new structure inside human cells: a never-before-seen twisted "knot" of DNA. Dubbed the "i-motif," this four-stranded knot looks totally different from the iconic ...

A new DNA structure inside human cells known as the “i-motif”, has been identified by scientists. This form resembles a twisted “knot” of DNA, instead of the well-known double helix first ...

Scientists have identified an entirely new kind of DNA inside humans. ... The i-motif looks like a twisted knot, as opposed to DNA’s well-known double helix structure.

When we think of the structure of DNA, the image that most likely comes to mind is that of the iconic double helix. Now, Australian scientists have found a new form, a twisted knot known as the i ...

Inside each cell of the human body are proteins that control which genes are expressed at the right place and time. However, ...

When the Empire State Building was constructed, its 102 stories rose above midtown one piece at a time, with each individual element combining to become, for 40 years, the world's tallest building.

A team of scientists has identified how damaged DNA molecules are repaired inside the human genome, a discovery that offers new insights into how the body works to ensure its health and how it ...

The scientists analyzed the structure of the connector – the core of the phi29 DNA packaging motor – to a resolution of 3.2 angstroms, or 3.2 hundred-millionths of a centimeter. Their findings show ...

As the DNA supercoils inside the nucleus, it twists and folds in different forms. Imagine twisting that telephone cord mentioned at the beginning, several times on itself.
