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 ...

Sir2, an enzyme belonging to sirtuins, has been shown to be involved in the deacetylation of proteins. Researchers from the ...

The goal of gene therapy is to permanently cure hereditary diseases. One of the most promising technologies for this is the ...

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 ...

Scientists from the Helmholtz Institute for RNA-based Infection Research (HIRI) and collaborating institutions have developed a DNA-editing method that introduces small chemical modifications at ...

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 ...

Your DNA holds the blueprint to build your body, but it’s a living document: Adjustments to the design can be made by epigenetic marks. Cataloguing these marks and how they work is important for ...

In humans and other eukaryotes, two principal epigenetic marks are known. A team has discovered a third, novel epigenetic mark -- one formerly known only in bacteria -- in bdelloid rotifers, small ...
