Correction to: Nature https://doi.org/10.1038/s41586-023-06323-x Published online 12 July 2023

In the version of this article initially published, there was an error in the legend for Fig. 2i, where in the text now reading “Schematic of the RNA duplex formed between Alu sequences in an SE351 eRNA and a CNN2 promoter RNA”, “CNN2” originally read “CFD”. The error has been corrected in the HTML and PDF versions of the article.
