R-loops are structures that form when a strand of RNA (red) forms a stable structure with double-stranded DNA, causing one strand of the DNA to form a loop. R-loops are associated with gene ...

There are many different ways in which the genetic material DNA can be damaged, resulting in the development of diseases such as cancer. Certain forms of DNA damage are associated with so-called ...

This new review article highlights the pivotal and paradoxical role of R-loops in maintaining genomic stability while simultaneously posing risks to it. These three-stranded nucleic acid structures, ...

A schematic showing how R-loops, a hybrid of RNA and DNA, can form during DNA transcription when the messenger RNA chain being assembled by the RNA polymerase binds to one of the DNA strands. R-loops ...

Kyle Miller and his team discovered a potential new target for drug therapies: structures in our DNA called R-loops. A human cancer cell that overexpresses the enzyme APOBEC3B (left) has fewer R-loops ...

New research reveals how the RapA enzyme protects against R-loop cytotoxicity in E. coli. Genetically speaking, it's a bacterium's worst-case scenario: during transcription, newly minted RNA sticks to ...

Not all DNA looks like the familiar double helix. Sometimes, parts of our genetic code fold into unusual shapes under certain conditions. One such structure known as a G-quadruplex (G4) looks like a ...

A study of newly created databases of medulloblastoma has found that patients with tumors containing circular extrachromosomal DNA -- loops of DNA found outside of regular chromosomes -- are twice as ...
