![The RDP network of molecular cell biology. A schematic representation of the autocatalytic (RAF) set arrangement of components and processes constituting the biosynthesis network for the production of new RNA, DNA and protein (i.e., RDP) strands in living cells (gray background). The monomer units of RNA, DNA, and protein strands—ribonucleoside triphosphates (rNTPs), deoxyribonucleoside triphosphates (dNTPs), and amino acids—are considered to represent raw materials (“food”) -- [q-bio.MN]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/10/System.png?resize=1200%2C718&ssl=1)
[q-bio.MN] Our guiding question for this article was: How did RNA adjust its life when the RNA world era came to an end? RNA has its practical execution side in […]

New Study Sheds Light on Ancient Protoribosome and its Role in Early Life Evolution
Scientists have uncovered new insights into the protoribosome, a molecular fossil within the ribosome, which plays a key role in the origin of life on Earth. This research, published in […]

A Conserved Ribosomal Protein Has Entirely Dissimilar Structures In Different Organisms
Ribosomes from different species can markedly differ in their composition by including dozens of ribosomal proteins that are unique to specific lineages but absent in others. However, it remains unknown […]
