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 ...

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 ...

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 ...

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.
