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 ...

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 ...

CRISPR—Clustered Regularly Interspaced Short Palindromic Repeats—is the microbial world’s answer to adaptive immunity. Bacteria don’t generate antibodies when they are invaded by a pathogen and then ...

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 ...

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 ...

If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by researchers at Goethe University Frankfurt, part of the Rhine-Main University ...

In white biotechnology, microorganisms serve as industrial bioreactors for large-scale production of fine chemicals, enzymes, active pharmaceutical ingredients, agro chemicals, and food additives. In ...
