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 ...

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 ...

Researchers created the most detailed maps yet of the genome’s three-dimensional organization using human stem cells and fibroblasts. The study reveals how DNA folding, looping and positioning ...

A team of researchers has generated one of the most detailed 3D maps of human chromosomes, cataloging over 140,000 DNA looping interactions.

The human genome is no longer just a sequence to be read. It’s a dynamic structure that twists, folds, and reshapes itself in ways that help determine how life functions at the cellular level.

The first crystal structure of an alternative DNA shape from the insulin gene has been revealed by a UCL-led research team. DNA is widely accepted to be formed of two strands that wind around one ...

Scientists depicted the four-dimensional genome model to reveal how DNA folding regulates genes. The discovery helps ...

James Dewey Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped launch a revolution in biology and medicine, died Thursday at age 97. He died in hospice care after a brief ...
