Epigenetic tags, for example, can be added to the genome; they impact gene expression, and researchers have only recently begun to understand how they work. Now scientists at the University of ...

The gastrointestinal system of most animals carries a colony of microbes known as the gut microbiome. Trillions of organisms are thought to live in the human gut microbiome, which has a powerful ...

While mutation and sexual reproduction drive genetic innovation in many eukaryotes, for life’s exclusively unicellular domains—archaea and bacteria—horizontal gene transfer is a critical mechanism for ...

Contrary to what’s typically described in biology textbooks, bacteria and archaea can have transcription proceed in opposite directions on the genome. This occurs thanks to bidirectional promoters—DNA ...

AIST researchers, in collaboration with JAMSTEC, Hokkaido University and Tohoku University, have succeeded in cultivating an ultrasmall bacterial strain parasitizing archaea and classified the ...

Archaea microbes might instead simply be contorting their DNA to turn genes on and off –– allowing proteins to “read” the genes when the Slinkies open, and cutting off access when they close.
