Guarding genes against damage is a crucial and complex job, so it’s to be expected that cells have several mechanisms to repair DNA breakages, each providing support under different circumstances. For ...

DNA repair is essential for the maintenance of genomic stability and its failure can lead to human disease. Various DNA repair systems exist, such as base excision repair, nucleotide excision repair, ...

New research sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells. The study demonstrates how these proteins ...

New research finds that the microscopic “water bears" are remarkably good at repairing their DNA after a huge blast of radiation. By Carl Zimmer To introduce her children to the hidden marvels of the ...

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

A repair system in our cells fixes DNA damage caused by exposure to ultraviolet (UV) light from the sun, however the detailed process behind this is not fully understood. An international research ...

Shape shifts happen all around you. Cells stretch, tissues curl, and living structures shift their form as naturally as breathing. Scientists have tried to copy those abilities for years, hoping to ...

Inside every human cell, six feet of DNA folds into a nucleus that is only a few micrometers wide, yet still manages to switch genes on and off with exquisite precision. The latest work on ...
