To many working biologists, DNA-modifying enzymes are tools, not unlike a pair of molecule-sized scissors. To Dr. Barry Stoddard, a professor in the Basic Sciences division at Fred Hutch, these ...
Enzymes that cut DNA at specific sites are called endonucleases; these enzymes play many roles in genomic replication, fidelity, and defense. The initial discovery of restriction endonucleases in the ...
The origin of SARS-CoV-2 remains unresolved. In a non-peer-reviewed preprint published on bioRxiv on Oct. 20, 2022 three authors present analyses that, according to their interpretation, suggest a ...
An important DNA modification is methylation, or the addition of a methyl group to the 5th carbon of cytosine. This forms 5-methylcytosine (5mC), typically associated with repression of gene ...
Researchers have uncovered the enzyme behind chromothripsis, a chaotic chromosome-shattering event seen in about one in four cancers. The enzyme, N4BP2, breaks apart DNA trapped in tiny cellular ...
A new family of enzymes enables precise cuts in single-stranded DNA, offering powerful new tools for genetic engineering and expanding possibilities in biotechnology. (Nanowerk News) A few years ago, ...
In crisis, the nucleus calls antioxidant enzymes to the rescue. The nucleus being metabolically active is a profound paradigm shift with implications for cancer research. In crisis, the nucleus calls ...
