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 ...

When a virus infects a bacterial cell, the viral genome is the first component to be fully injected into the cell, making it an ideal immune target. A bacterial enzyme anchored to the membrane ...

Researchers at the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine) have developed 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 ...

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, ...

DNA is often seen as the blueprint of life—carrying the code to govern the development and traits of an organism—but “there are things beyond the DNA sequence,” says Xiaoqi Feng, a plant geneticist at ...

There are many health problems that can be traced back to errors in the genetic code. There are also many potential benefits to genetic engineering outside of healthcare. Nature has already found ways ...

The new study reveals a remarkable way that cells keep us safe from transposable elements (TEs) gone wild. The researchers found that cells have taken advantage of an entire protein network to repress ...

Today (September 19), the Lasker Foundation announced this year’s winners of the Lasker Awards. Zhijian “James” Chen, a biochemist at the University of Texas Southwestern Medical Center, was awarded ...
