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 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 ...

A team has unearthed new findings about what happens during the minutes and hours after a cell divides, expanding our understanding of human biology -- and potentially leading to better medicines. DNA ...

Plasmids, small circular DNA molecules found in bacteria, may contain antibiotic-resistance genes and have the ability to replicate independently. Bacteria can transfer these plasmids to one another, ...

DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...

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 ...

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 ...

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 ...

In July 2022, the World Health Organization (WHO) announced that monkeypox was a public health emergency of international concern. And, as of early December 2022, more than 82,000 human monkeypox ...
