The presence of the nucleobases in the samples reinforces the hypothesis that carbonaceous asteroids contributed to the prebiotic chemical inventory of the early Earth.

A sample collected by the Hayabusa 2 spacecraft from the spinning top-like asteroid contained the nucleobases adenine, ...

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 ...

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 ...
