CRISPR functions as a programmable genetic memory system derived from bacterial immune defenses against viral infections. Guide RNA allows for rapid multiplexed targeting compared to older ...

Genome editing-based therapies typically aim to treat disease by correcting underlying genetic mutations in patient's cells. However, most genetic disorders are caused by dozens or even thousands of ...

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 ...

DNA is packaged inside cells with the double helix tightly coiled around histone proteins (yellow) that form nucleosomes. These are then coiled together and further packaged into chromosomes (far ...

Cold Spring Harbor Laboratory, Watson's former employer, confirmed the American scientist's death on Nov. 7 Abigail Adams is a Human Interest Writer-Reporter for PEOPLE. DANIEL MORDZINSKI/AFP via ...

Molecular Biologist Dr. James Watson attends the 10th Anniversary Sing For Hope Gala at Tribeca Rooftop on October 24, 2016 in New York City. Editor at Large There’s no telling how the history of ...

James Watson, one of the discoverers of the structure of DNA, has died in a New York hospice facility at the age of 97. Along with fellow researchers Francis Crick and Maurice Wilkins, he won the 1962 ...
