Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...

In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

Newly developed DNA nanostructures can form flexible, fluid, and stimuli-responsive condensates without relying on chemical cross-linking, report researchers from the Institute of Science Tokyo and ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...

While the central dogma of molecular biology outlines the linear flow of genetic information from DNA to RNA to proteins (black lines), glycomics introduces a “3rd code of life”—glycans—that operates ...

Drawing inspiration from natural cell signaling cascades, chemists at Université de Montréal (UdeM) have developed a DNA-based signaling cascade that allows them to quantify and report via an easily ...

A naked mole rat with its head raised and nose in the air. Long live the naked mole rat. These wrinkly critters live about 37 years, thanks in part to an enzyme that helps regulate DNA repair. Credit: ...

Two teams of researchers have uncovered microscopic details of how a protein called photolyase uses light to repair DNA. The discovery could help develop sustainable technologies for chemical ...

A new CRISPR breakthrough shows scientists can turn genes back on without cutting DNA, by removing chemical tags that act ...
