New analytical methods developed at Baylor College of Medicine and collaborating institutions have increased our understanding of how bacteria manage DNA. The methods enabled researchers to uncover ...

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 ...

Tiny tweaks in DNA folding can have big effects. A study from Umeå University shows that even the most subtle changes in DNA's shape have an important influence on gene activity and energy production.

Cyanobacteria—ancient microbes that oxygenated Earth and made complex life possible—are still revealing surprises billions of ...

DNA–protein cross-links (DPCs) represent a severe form of DNA damage that can disrupt essential chromatin-based processes. Among them, DNA–histone cross-links (DHCs) occur frequently within ...

Chemical structure of guanine, showing its double-ring purine structure and the functional groups involved in hydrogen bonding with cytosine. (Image: Public Domain) Guanine has the chemical formula ...

Scientists have captured the most detailed structural images to date of a specific type of protein's DNA repair process, a ...

Estrogen is known as an important hormone, and it can control many cellular and bodily functions by regulating the activity of hundreds of genes. Scientists have now learned more about how estrogen ...

James D. Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped light the long fuse on a revolution in medicine, crimefighting, genealogy and ethics, has died, according to ...
