Which of the following is considered a method of horizontal gene transfer in bacteria?
A) binary fission only
B) transformation and binary fission
C) conjugation and budding
D) transduction and conjugation only
E) conjugation, transformation, and transduction
Horizontal Gene Transfer
The movement of genetic material between unicellular and/or multicellular organisms other than by the "vertical" transmission of DNA from parent to offspring.
Transformation
Taking up of extraneous genetic material from the environment by bacteria.
Transduction
Exchange of DNA between bacteria by means of a bacteriophage.

Final Answer :
E
Explanation :
Horizontal gene transfer refers to the transfer of genetic material between organisms that are not related by descent. In bacteria, there are three main methods of horizontal gene transfer: conjugation, transformation, and transduction. Therefore, the best choice is E, which includes all three methods. Binary fission and budding are not methods of horizontal gene transfer.
