Archaea
Archaea are a group of single-celled microorganisms that share some similarities with bacteria. Archaea live in extreme environments such as places with very high temperatures and salt concentrations. Archaea lack cell nuclei and have a unique cell wall structure that enables them to survive in such hostile environments.

Prokaryotes have long been at war with bacteriophage. The evolutionary pressure of this struggle has led both sides to develop sophisticated defenses. Notably, CRISPR-Cas systems evolved to l...
