Question

Which of the following method is used in horizontal gene transfer?

• A. Transduction
• B. Conjugation
• C. Transformation
• D. All of the above

Answer 1

The correct option is D All of the above

The horizontal gene transfer is the method in which there is a transfer of the gene into the cell and no form of reproduction is performed. The gene which is transferred is responsible for the characters in the same cell in which it gets inserted. There are three methods by which horizontal gene transfer can be performed. The method of transfection or transduction is used when there is the transfer of the gene into the cell with the help of virus or phage.

Conjugation is the method in which the gene of the plasmid is transferred from one (F${}^{+}$) bacterial cell to the other (F${}^{-}$) cell.

Transformation is the method in which the cells which are compatible can take up the gene or the desired nucleic acid from the medium.

Thus, the correct answer is option D.
