In a new study, using three-letter “triplet” RNA, scientists induced RNA replication by preventing the RNA double helix from zipping together. Where did we all come from? It’s a question that has lit ...

They propose that RNA replication is possible without the presence of any enzymes at all. Instead, it's possible to perform surface-assisted copying of immobilized RNA.

Most of the major conditions required for RNA to replicate, possibly the key stage in kick-starting life, were probably met ...

Scientists have created an artificial RNA system that can copy itself using simple building blocks and temperature changes.

The replication of positive-sense RNA ((+)RNA) viruses involves numerous interactions between the RNA and proteins of the virus and proteins, membranes and lipids of the host. Host factors are ...

RNA strands zip up into a double helix that blocks their replication. Like Velcro, these are hard to pull apart and quick to stick back together, leaving no time to copy them.

In a recent study posted to bioRxiv*, researchers evaluated the early replication kinetics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Study: Visualization of early RNA ...

The COVID pandemic illustrated how urgently we need antiviral medications capable of treating coronavirus infections. To aid ...

Plant RNA viruses pose a significant threat to global agriculture, affecting a vast array of crop species and leading to ...

HDV RNA Replication With mRNA synthesis in full swing, the next step of the replication process can begin: amplification of genomic RNA. For this, the genomic RNA must first travel to the ...

(1) ChatGPT provides a nice explanation of how RNA strand damage contributes to mutation. I didn't dare put this in the article for fear of hate mail. Or worse. "The 2' hydroxyl group is directly ...

“The triplet or three-letter building blocks of RNA we used, called trinucleotides, do not occur in biology today, but they allow for much easier replication.
