University of Missouri scientists build rewritable DNA hard drive using nanopore sensor for storing and editing digital data.

According to the RNA world hypothesis, life began when RNA molecules evolved the ability to make more copies of themselves. Now we have discovered an RNA molecule that is almost capable of this – it ...

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 ...

Researchers in Shenzhen, China, have built a “cassette tape” that stores digital data as DNA strands on a thin plastic tape. A single prototype holds 36 petabytes, which is about one million gigabytes ...

A new study reveals how cells activate an emergency DNA repair system when their usual defenses fail, especially under the stress of tangled RNA–DNA structures called R-loops. Credit: Stock Scripps ...

The authors attempt to use sequencing of nascent DNA (DNA linked to an RNA primer, "SNS-Seq") to localise DNA replication origins in Trypanosoma brucei, but they analyse the results for only part of ...

You can always be judged by your scars. This is the idea that sums up what researchers at Spanish National Cancer Research Centre (CNIO) claim is one of the new breakthroughs in basic and biomedical ...

Plectonemes are the analog of the twisted tangles of telephone cords, and can form in DNA that is pulled through a nanoscale channel. They are called plectonemes. They are the analog of the twisted ...

They are called plectonemes. They are the analog of the twisted tangles of telephone cords, and can form in DNA that is pulled through a nanoscale channel. This is the finding of a study led by Ulrich ...

ABSTRACT: Biodosimetry, a technique for estimating radiation doses by assessing chromosomal aberrations in both accidental and occupational exposures, has played a crucial role in radiological ...
