Chemical structure of guanine, showing its double-ring purine structure and the functional groups involved in hydrogen bonding with cytosine. (Image: Public Domain) Guanine has the chemical formula ...
A new study by NYU chemists finds that DNA tiles can assemble into 3D structures without the sticky cohesion of hydrogen bonding. This finding, published in Nature Communications, turns a fundamental ...
