Capturing DNA origami folding with a new dynamic model

Most people are familiar with the DNA double-helix. Its twisted ladder shape forms because the long pieces of DNA that make up our genome are exactly complementary—every adenine paired to a thymine, and every cytosine paired ...

Developing a machine learning model to explore DNA methylation

A Northwestern Medicine study has detailed the development of a machine learning model to predict DNA methylation status in cell-free DNA by its fragmentation patterns, according to findings published in Nature Communications.

Biologists reveal how gyrase resolves DNA entanglements

Picture in your mind a traditional "landline" telephone with a coiled cord connecting the handset to the phone. The coiled telephone cord and the DNA double helix that stores the genetic material in every cell in the body ...

Newly discovered protein prevents DNA triplication

Every time a cell divides, its DNA is duplicated so that the two daughter cells have the same genetic material as their parent. This means that, millions of times a day, a biochemical wonder takes place in the body: the copying ...

Study shows how proteins guide electrons to the right place

Cells need energy to function. Researchers at the University of Gothenburg can now explain how energy is guided in the cell by small atomic movements to reach its destination in the protein. Imitating these structural changes ...

The improbable origins of life on Earth

We do not yet know how, where, or why life first appeared on our planet. Part of the difficulty is that "life" has no strict, universally agreed-upon definition.
