Cryo-EM reveals how '911' molecule helps fix damaged DNA

When something goes wrong during DNA replication, cells call their own version of 911 to pause the process and fix the problem—a failsafe that is critical to maintaining health and staving off disease.

DNA replication under the microscope

Cryogenic electron microscopy (cryo-EM) has enabled researchers to study how the DNA replication machinery assembles at sites where DNA is damaged.

Machine learning predicts antibiotic resistance spread

Genes aren't only inherited through birth. Bacteria have the ability to pass genes to each other, or pick them up from their environment, through a process called horizonal gene transfer, which is a major culprit in the spread ...

Understanding the origin of genetic instability

Researchers at the Andalusian Molecular Biology and Regenerative Medicine Centre (CABIMER) and the University of Seville have taken another step in the study of genetic instability, as manifested in cancer cells. This has ...

New technique illuminates DNA helix

Cornell researchers have identified a new way to measure DNA torsional stiffness—how much resistance the helix offers when twisted—information that can potentially shed light on how cells work.
