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 ...

Standard genetic sequencing approaches can tell you a lot about the genetic makeup and activity in a sample, like a piece of tissue or drop of blood. But they don't tell you where specific genetic ...

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 ...

The graphic shows images of a cell under mtDNA replication stress made using so-called Correlative Light and Electron Microscopy (for short: CLEM). The mitochondrial DNA (mtDNA, green) is ejected from ...

A 'biological camera' bypasses the constraints of current DNA storage methods, harnessing living cells and their inherent biological mechanisms to encode and store data. This represents a significant ...

Researchers at California NanoSystems Institute at UCLA, Stockholm University and Uppsala University are working on a smartphone-based microscope in hopes of developing a cost-effective and accessible ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

Scientists created shapeshifting DNA robots that react to acidity, opening paths to smart drug delivery, pollution cleanup, and advanced data storage. (Nanowerk News) Researchers at the University of ...
