Scientists reveal a hidden second layer of human DNA, showing how genome folding controls genes and influences disease development.

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 ...

On February 28, 1953, two scientists, James Watson and Francis Crick, announced they had figured out the structure of DNA. DNA or deoxyribonucleic acid, is the hereditary material in humans and almost ...

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 ...

The genome is more than a linear code; it is a dynamic structure whose three-dimensional folding dictates how genes are regulated. Traditional sequencing technologies capture base-level variation but ...

Researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a potential therapeutic target in cancer. Every day, billions of cells in your body ...

This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...
