Question

When new genetic material enters a bacterial cell through conjugation, transformation, or transduction, a merodiploid cell can be formed. Does this happen with the V. cholerae bacteria?

No, it cannot produce merodiploid cells because merodiploid cells can be produced only when entire genomes enter cells. Yes, it produces permanent merodiploid cells because the newly introduced DNA has a replication origin. Yes, it produces temporary merodiploid cells between the time the genetic material enters the cell and the time that recombination occurs. No, it cannot produce merodiploid cells because bacterial cells must always be haploid. Yes, it can, but only very briefly because the new genetic material is integrated back into the chromosome instead of undergoing recombination.

Explanation / Answer

Following is the correct option:

Yes, it produces temporary merodiploid cells between the time the genetic material enters the cell and the time that recombination occurs.
