This image illustrates the chemical structure of a purine molecule, highlighting the numbering of the carbon and nitrogen atoms. The purine structure consists of a pyrimidine ring (positions 1 to 6) ...

A new study adds to an emerging, radically new picture of how bacterial cells continually repair faulty sections of their DNA. Published online May 16 in the journal Cell, the report describes the ...

Researchers have captured the first atomic-level views of human SMUG1, a key enzyme involved in repairing damaged DNA.

Despite these advances, the synthesis of DNA nanostructures has remained a largely manual and time-consuming process. Traditional approaches often require the precise mixing of hundreds of unique DNA ...

Every cell in every organism on Earth copies DNA the same way. Except one bacterial protein — quietly doing something ...
