CRISPR-like ‘immune’ system discovered in giant virus

Giant mimiviruses fend off invaders using defences similar to the CRISPR system deployed by bacteria and other microorganisms. Like prokaryotes, mimiviruses are plagued by viruses known as virophages. This appears to have led to the evolution of a defence system … Continue reading
