DNA restriction-modification enzymes are enzymes involved in DNA restriction modification. They include DNA restriction endonucleases (restriction enzymes) and their companion modification methylase ...

Cellular RNAs are chemically modified by many RNA modification enzymes; however, often the functions of modifications remain unclear, such as for pseudouridine formation in the tRNA TΨC arm by 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 have identified a function for a mysterious DNA modification in fruit flies' brain development, which may provide hints to its role in humans. Emory scientists have identified a function ...

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 ...
