When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular aging, cancer, ...

Researchers at the University of Eastern Finland have discovered a novel mechanism safeguarding mitochondrial DNA. The study, published in PNAS earlier this week, was carried out in close ...

When a cell begins to copy itself, it must undergo DNA replication, in which the first step is the separation of the two DNA strands so that each can be used as a template for a new DNA. The strand ...

In a study that appears in the journal Cell, scientists from San Francisco-based Gladstone Institutes—including co-first author Megan Ostrowski (left) and senior author Vijay Ramani, PhD ...

Scientists have captured the first detailed 'molecular movie' showing DNA being unzipped at the atomic level -- revealing how cells begin the crucial process of copying their genetic material.

Nobody wants to be average. But for a long time, scientists have found it convenient to think of bacterial cells as just that: "average." Researchers have traditionally relied on population-level ...
