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 a new type of genetic replication system which demonstrates how the first life on Earth -- in the form of RNA -- could have replicated itself. The scientists say the new ...

Long-term TcRR experiment increases replication ability. We first performed a long-term TcRR experiment under conditions in which the RNA amplification was assisted by reverse transcription and ...

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

Viral Reorganization of the Secretory Pathway Generates Distinct Organelles for RNA Replication. Cell , 2010; 141 (5): 799 DOI: 10.1016/j.cell.2010.03.050 Cite This Page : ...

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.

Within an infected cell, viral RNA replication occurs at modified cellular membranes, often in association with spherules, virus-induced vesicles approximately 50–100 nanometers in size.

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 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.
