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

At some point, RNA must have replicated itself before the evolutionary arrival of DNA and proteins, and now we might know how.

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

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 ...

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

Triplet RNA building blocks, combined with freeze-thaw cycles and pH changes in water, enable RNA self-replication without enzymes, overcoming barriers posed by double-helix formation.

g, Quantitative analysis of RNA replication using TaqMan real-time RT–PCR. Total cellular RNA was isolated at 6, 10, 14, 24 and 48 h after transfection with the Rep- LacZ RNA.

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 ...

This video illustrates the molecular assembly of the “proto-crown” core of the RNA virus genome replication complex. This ringed assembly contains 12 adjacent copies of a single large viral ...

Novel RNA nanomedicine reduces HIV replication by 73%, study finds. Written by Corrie Pelc on February 25, 2024 — Fact checked by Sarah Myers, PharmD. Share on Pinterest andresr/Getty Images.

Both DNA and RNA are built with a sugar backbone, but whereas the sugar in DNA is called deoxyribose (left in image), the sugar in RNA is called simply ribose (right in image). The "deoxy" prefix ...

For 400 million years, a leading hypothesis claims, Earth was an “RNA World,” meaning that life must’ve first replicated from RNA before the arrival of proteins and DNA.
