Life on Earth depends on the ability of cells to duplicate their genetic material, encoded in DNA molecules, and pass this information on to the next generation. Elucidation of the molecular mechanism ...
Every person starts as just one fertilized egg. By adulthood, that single cell has turned into roughly 37 trillion cells, many of which keep dividing to create the same amount of fresh human cells ...
As cells divide, they must copy all of their chromosomes once and only once, or chaos would ensue. How do they do it? By Amber Dance/Knowable Magazine Published Jul 7, 2023 6:00 PM EDT This article ...
DNA, which has a double-helix structure, can have many genetic mutations and variations. Credit: NIH When cells in the human body divide, they must first make accurate copies of their DNA. The DNA ...
Visualizing and quantifying DNA replication dynamics in living human cells remains challenging. Here, a new super-resolution ...
DNA replication is one of the most important processes in biology, responsible for ensuring that a cell's genetic material is copied over to new cells efficiently during cell division. But what ...

Mayo Clinic researchers discover ‘traffic controller’ protein that protects DNA, and may help kill cancer cells
Mayo Clinic researchers have identified a protein that acts like a traffic controller for DNA, preventing damage during cell division — a discovery that could lead to new cancer therapies, according ...
In a twist on the question, "Which came first, the chicken or the egg?", scientists have long faced a similar question about how human adenovirus replicates: "Which comes first, assembly of the viral ...
An elegant collaboration between researchers in the UK's two core-funded Medical Research Council Research Institutes, the Laboratory of Medical Sciences (LMS) in London and the Laboratory of ...
Reimagined undergrad class teaches students entire DNA sequencing process using cutting-edge devices
Students take samples of water and the microscopic creatures within at the Alviso Marina County Park. (Image by Erika Cardema) At the Alviso Marina County Park, reddish-brown water laps at the edge of ...
If the engines of DNA replication stay in high gear all the time, they eventually stall or even break down. Fortunately, these engines, which consist of protein complexes, have what could be called ...
