Tantalizing clues in 4-billion-year-old asteroid Bennu samples could reveal particular molecular formations that some ...

Scientists have found special chemical compounds necessary for the existence of life in samples collected from asteroid Bennu ...

NASA has spent the first 100 days of the Trump-Vance Administration continually exploring, innovating, and inspiring.

Ciesla and Sanford say this process could have generated organic molecules such as amino acids, amphiphiles and nucleobases—the building blocks of proteins, cell membranes and RNA and DNA ...

Plant-specific Dof proteins simultaneously recognize AAAG nucleobases and a nearby minor groove, enabling directional expansion of the major groove for tandem sequence binding. This mode allows ...

In this work, we investigate the ability of TDG to excise modified nucleobases from the simplest unit of compacted DNA, the nucleosome core particle (NCP). We measure TDG activity on a population of ...
