Photos and letters show how James Watson and Francis Crick raced to uncover the double helix structure of DNA.

James D. Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped light the long fuse on a revolution ...

Cancer genomes are the result of diverse mutation processes that have often accumulated over decades. Scientists have analyzed the molecular evolution of tumors after exposure to mutagenic chemicals.

Brains with chronic traumatic encephalopathy (CTE) show DNA damage similar to Alzheimer’s. Study links genetic stress to brain degeneration.

Mutations are changes in the molecular "letters" that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...

Using an atomic force microscope tip as a pen and different single-stranded DNA as inks, scientists at Northwestern University have demonstrated a technique that could lead to the ultimate ...

Similarly to the artistic technique of folding paper into ornate shapes, DNA origami is a self-assembling technique of precisely folding single-stranded DNA scaffolds into well-defined nanostructures.

CHAMPAIGN, Ill. — Researchers report that a single-stranded DNA-binding protein (SSB), once thought to be a static player among the many molecules that interact with DNA, actually moves back and forth ...
