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 ...

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 ...

As tough as medieval chainmail armor and as soft as a contact lens. This material is not taken from science fiction, it is a ...

If stretched out, human DNA would be about 2 meters long. For this long strand to fit inside the cell nucleus, which is about ...

High-resolution imaging has revealed the internal layout of chromatin condensates, showing how DNA fibers fold and interact ...

Deep in coastal mangroves and even inside our own mouths, biologists are finding that DNA does not always sit in a simple ...

Inside every human cell, six feet of DNA folds into a nucleus that is only a few micrometers wide, yet still manages to ...

DNA might be too small to see with the unaided eye, but it packs our cells in shocking quantities: More than six and a half feet of DNA lies within every cellular nucleus. It squeezes into such a ...

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.

New work from UC Davis and the University of Utah shows how the 3D structure of DNA inside a germ cell commits it to develop into a sperm cell. The discovery could improve understanding of fertility ...
