One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published ...

In a landmark effort to understand how the physical structure of our DNA influences human biology, Northwestern investigators ...

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 ...

High-resolution imaging has revealed the internal layout of chromatin condensates, showing how DNA fibers fold and interact within these droplet-like structures. The findings connect molecular ...

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 ...

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 ...

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

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 ...
