Chromosomes are masters of organization. These long strings of DNA fold down into an ensemble of compact structures that keep needed parts of the genome accessible while tucking away those that aren’t ...

The first crystal structure of an alternative DNA shape from the insulin gene has been revealed. The first crystal structure of an alternative DNA shape from the insulin gene has been revealed by a ...

For decades, scientists believed a fertilized egg’s DNA began as a shapeless mass, only organizing itself once the embryo switched on its genes. But new research reveals that the genome is already ...

In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

Researchers have mapped 50,000 of DNA's mysterious "knots" in the human genome. The innovative study of DNA's hidden structures may open up new approaches for treatment and diagnosis of diseases, ...

A screenshot of a Google Doodle, which is drawn in light and dark purple and shows a cartoonish DNA double helix, the structure of guanine and a phosphate group, and small cartoons of a chromosome and ...

Replication origins in Trypanosoma brucei integrate multiple features previously described individually in opisthokonts, revealing a unified structural topology built from strand-specific nucleotide ...
