Transcription activator-like effector nucleases are readily targetable 'molecular scissors' for genome engineering applications. These artificial nucleases offer high specificity coupled with simplicity in design that results from the ability to serially chain transcription activator-like effector repeat arrays to target individual DNA bases. However, these benefits come at the cost of an appre...
Gold nanoparticles were modified with RNA and utilized to detect specific DNA sequences and various RNA nucleases.
Viruses have been used to deliver two types of site-specific nucleases into cells for targeted gene editing.

In vitro selection experiments have produced nucleic acid ligands (aptamers) that bind tightly and specifically to a great variety of target biomolecules. The utility of aptamers is often limited by their vulnerability to nucleases present in biological materials. One way to circumvent this problem is to select an aptamer that binds the enantiomer of the target, then synthesize the enantiomer o...
Preferential sensitivity of specific genes in chromatin to the action of bleomycin in different cell types was investigated using restriction enzyme digestion of DNA from drug-treated nuclei in combination with the Southern blotting procedure. The results show that the highly active ovalbumin gene in laying hen oviduct nuclei is more sensitive than the inactive globin gene to the digestion by b...
Ribonuclease H from human KB cells, chick embryos, calf thymus, avian myeloblastosis virus, and Rous associated virus specifically degrades the RNA of DNA.RNA hybrids, producing mono- and oligoribonucleotides terminated in 5'-phosphates. The cellular RNase H is an endonuclease, whereas the viral enzyme appears to be an exonuclease. Viral DNA polymerase and RNase H copurify through all separatio...
