The main structure, a dimer, inhibits RCS but can be reactivated making way for potential double RCS.

Overall, the paper emphasizes the importance of template structure for self-replication and offers new insights into how the initial replication machinery might have looked and functioned.

In the paper, we investigate RNA polymerase ribozymes and their ability to perform rolling circle synthesis (RCS).

We previously showed that RCS is possible, though inefficient. Now, we use cryo-EM and identify a network of unexpected structures (see movie) which affect RCS.

Roles of dimeric intermediates in RNA-catalyzed rolling circle synthesis
Abstract. The RNA world hypothesis is supported by the discovery of RNA polymerase ribozymes that can perform RNA-catalyzed RNA replication processes on di

Just received this super cool comic book on the origins of life in the RNA world! Great work! ❤️

Very excited to announce our Origins of Life Seminar in the summer of 2025 at the Royal Danish Academy of Sciences and Letters!!!

The meeting will focus on bridging the distances in which life works - from light years to nanometers. 📐

Checkout our great speaker-list and stay tuned for more!

The Cryo-EM: the next 50 years Symposium held yesterday at @ucberkeleyofficial.bsky.social was a smashing success!!

Very interesting program at the Cryo-EM: next 50 years symposium at Berkely. Solving more RNA structures is on the todo!

Conclusions from RNA section at #CASP16, without a template all fail. All small targets had a template.

Looking at the 2D structure of the heterodimeric triplet polymerase ribozyme (TPR), always reminds me of the bronze-age petroglyphs of the plow driven by oxes 😅

Cool example that evolution likes cooperativity.
