We discussed the transfer of plasmids from cell to cell by conjugation. Do you think that plasmids could also be transferred from cell to cell by transformation (natural, not artificial)? Why do you think that? Do you think that plasmids could also be transferred from cell to cell by transduction? Why do you think that? (Hint: The answers are not “Because that’s not how it happens.” Consider the mechanisms of transformation and transduction as you write your answer).

Explanation / Answer

Transformation: Transformation is the process of gene transfer that involves absorption of genetic material through cell membrane. It requires the presence of intervening external medium. The absorbed genetic material is integrated with the host DNA resulting in its genetic expression in the host cell.

Plasmids could also be transferred from cell to cell by transformation. Antibiotic resistance is transferred between bacteria by plasmid transformation. The transforming plasmid contains gene that confers resistance to a particular antibiotic.

Transduction: Transduction is the process of transfer of genetic material between bacteria with the help of bacteriophage. Transduction happens either through the lytic cycle or lysogenic cycle. Recently, plasmid transfer from cell to cell by transduction has been demonstrated in Streptococcus thermophilus to Lactobacillus lactis.
