How a cell untangles entangled RNA

Transposons can turn cellular RNA into a tangle from which it is impossible to extract information. However, the cell has proteins that can easily unravel such a tangle.

Extracellular DNA: A Story in five questions

DNA can be detected not only inside cells, but also outside – such molecules are called extracellular DNA (vcDNA). They exist by themselves and affect the surrounding cells.
