Depiction of huge bacteriophages (red, left) and normal phages infecting a bacterial cell. The huge phage injects its DNA into the host cell, where Cas proteins -- part of the CRISPR immune system typically found only in bacteria and archaea -- manipulate the host cell’s response to other viruses. The authors have not yet photographed any huge phages, so all are depicted resembling the most common type of phage, T4. Image credit: Jill Banfield Lab / University of California, Berkeley.
