DNA is found in nearly all living cells. However, its exact location within a cell depends on whether that cell possesses a special membrane-bound organelle called a nucleus.

In our bodies, there are trillions of cells. DNA is the foundation of organisms, but what does it stand for? Get to know more about this nucleic acid.

New Twisted 'Knot' Human DNA Structure Discovered—and It Looks Nothing Like the Double Helix Published Apr 23, 2018 at 12:58 PM EDT Updated Apr 23, 2018 at 1:53 PM EDT By ...

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 ...

Bacteria have a special protein to repair breaks in DNA, and this can help us learn more about how it works, and how to stop it. Humam cells have their own DNA-repair mechanisms, and one protein ...

In 1963, Popular Science reported on the Nobel Prize-winning discovery, and Rosalind Franklin⁠—the woman who was left out of the accolades.

Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such structure, the G-quadruplex (G4), looks like a knot. These knots can ...

4-Strand DNA Structure Found in Cells. A newly discovered unusual nucleic-acid structure might have a role in regulating some genes. By Alison Abbott & Nature magazine.

From the eight stem cells, processed individually, the researchers captured between 37,000 and 122,000 DNA junctions. This represents just 1.2 to 4.1 percent of the total possible junctions that ...

DNA nanorobots can alter artificial cells Date: January 13, 2025 Source: Universitaet Stuttgart Summary: Scientists have succeeded in controlling the structure and function of biological membranes ...

In fact, studies in cancer cells have shown that small molecules that bind and stabilize G-quadruplex structures cause DNA damage at telomeres, supporting the argument 3.
