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 ...

The human genome has to be carefully organized so it will fit inside of the nuclei of cells, while also remaining accessible ...

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 ...

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 ...

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 ...

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 ...
