Question
Unlike Archaea, these organisms have evolved anti-anti-CRISPR systems that inactivate viral anti-CRISPR proteins. For 10 points each:
[10e] Name this domain of prokaryotic microbes that use CRISPR to fight off infection by phages.
ANSWER: Bacteria [or bacterium; accept Eubacteria]
[10h] Anti-CRISPRs and anti-anti-CRISPRs were discovered by biologists studying this genus of bacteria and its phages. Species in this genus include fluorescens, putida (“poo-TEE-duh”), and aeruginosa (“uh-ROO-jin-oh-suh”).
ANSWER: Pseudomonas
[10m] So far, anti-archaeal CRISPRs have only been observed in a virus named for one of these objects. Bacterial morphology is classified as spherical, spiral, or the shape of one of these objects.
ANSWER: rods [or rod-shaped bacteria; or rodlike; prompt on bacillus or bacilli]
