R loops consist of RNA–DNA hybrids that accumulate at preferred regions all over the genome, such as pericentromeric DNA, telomeres, ribosomal DNA or transcription termination regions. R loops are an ...

Loops at the ends of telomeres play a vital protective role preventing damage to chromosomes, according to new research. The study showed how the winding and unwinding of 't-loops' at the end of ...

G-protein-coupled receptors are membrane proteins that are regulated by a small family of arrestin proteins. During formation of the arrestin–receptor complex, arrestin first interacts with the ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature. Chromosomes are thread-like structures that carry a cell's ...
