parasitism Archives

An idealized schematic for some of the key sequential events in the establishment of the ribosome, starting from the situation in which a parasitic RNA takes advantage of a membrane-bound protocell containing ribonucleotide and amino acid resources used in viral replication, and graduating to a mutualism in which the host cell provides all of the ingredients essential to ribosome replication, and the ribosome engages with host mRNAs to produce proteins of joint utility.

A Parasitic Origin For The Ribosome?

by Keith CowingFebruary 25, 2026February 25, 2026

Ribosomes are the components of cells that read RNA and build proteins. Without the ribosome, the chemistry of life would still be catalyzed by raw RNA. And yet the origin […]

Novel Bacteria That Parasitize Archaea

by Keith CowingFebruary 11, 2025

AIST researchers, in collaboration with JAMSTEC, Hokkaido University and Tohoku University, have succeeded in cultivating an ultrasmall bacterial strain parasitizing archaea and classified the strain PMX.108T as new species and […]
