Scientists have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, actually plays a key role in ensuring fast and reliable replication—an insight ...

Researchers have gained a clearer insight into how common alterations to the structure of DNA affect the process of DNA replication. These structural changes can put a stop to replication, causing ...

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 ...

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 ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified in a new study. In a new paper published in Nature Communications, an ...

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 ...

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 ...

Retrotransposons are sequences of DNA in animal genomes that can replicate and reinsert themselves back into the genome. Experiments in flies and other model systems reveal that retrotransposons ...

Researchers at The University of Texas Medical Branch (UTMB) have identified how a key enzyme called ATR protects DNA from ...

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 ...

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...
