Bacterial reverse transcriptase (RT) is responsible for the production of an RNA-DNA complex called multicopy single-stranded DNA (msDNA). The genetic element required for the sysnthesis of msDNA is named a retron. Here, we characterize two novel retrons named retron-Vc81 and retron-Vc137 in Vibrio cholerae. Interestingly, retron-Vc81 and retron-Vc137 are replaced by retron-Vc95 at the same location on the chromosome.
