Answer: Retrovirus
Notes: Researchers have identified a protein, Neo, in Klebsiella pneumoniae that counters bacteriophage infections by halting replication. Neo is produced via a process involving Reverse Transcriptase (RTs) and non-coding RNA. RTs are enzymes that synthesize DNA from RNA templates, crucial for retroviruses like HIV. This discovery showcases RT's diverse role in bacterial defense and hints at its potential in biotechnology and medicine, particularly in combating antimicrobial resistance.
