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 ...

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 ...

DNA, often called the blueprint of life, is built from four chemical building blocks known as deoxy-nucleoside triphosphates (dNTPs)—dATP, dTTP, dGTP, and dCTP. Cells constantly need these molecules ...
