DNA's iconic double helix does more than "just" store genetic information. Under certain conditions it can temporarily fold into unusual shapes. Researchers at Umeå University, Sweden, have now shown ...

What is it, biologically, that makes me 'me'? The biggest reason is our unique genes, our so-called 'DNA.' DNA is known to form a 'double helix' structure, where two strands are paired and twisted.

A schematic of chromosome and DNA structure in the cell nucleus. Zooming into a cell reveals chromosomes inside the nucleus, and unwinding a chromosome reveals the DNA double helix. The 4D Nucleome ...

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 described by ...

When James Michael Creeth finished adding acid to the sample of DNA taken from a calf’s thymus gland, he wasn’t just completing the experiments that would earn him his PhD. He was paving the way for a ...

Sixty years ago today the journal Nature published a single-page article containing a solitary figure of two intertwined ribbons. This image, or versions of it, are now so familiar that they are ...

The human genome has to be carefully organized so it will fit inside of the nuclei of cells, while also remaining accessible to the cellular machinery that works to express the right genes at the ...

One of the most important milestones in modern science, does April 25 also mark the date of an intellectual heist? As has been well-documented, a third person contributed to the discovery — the ...

A previously overlooked letter and a news article that was never published, both written in 1953, add to other lines of evidence showing Rosalind Franklin was an equal contributor — not a victim — in ...

A study in the Chinese Journal of Natural Medicines reports the first high-resolution structure of the major G-quadruplex in the TMPRSS2 promoter and shows how berberine binds and stabilizes it, ...
