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 ...

For years, biomolecular condensates were thought to be simple, liquid-like droplets with little internal organization. New ...

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–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 ...

DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave. Researchers have now mapped this hidden architecture in unprecedented detail, showing ...

A change in the DNA sequence of a codon may not change the corresponding amino acid residue in the encoded protein because each residue can be encoded by several codons. This is called the Wobble ...

One of the most important milestones in modern science, does April 25 also mark the date of an intellectual heist? As has been well-documented, a third person contributed to the discovery — the ...

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 ...

For James Watson, DNA was everything — not just his life's work, but the secret of life itself. Over his long and storied career, Watson arguably did more than any other scientist to transform a ...
