All of the following cause genetic change in bacteria EXCEPT:

a. Mutuation

b. Conjugation

c. Transduction

d. Transformation

e. Binary fission

Genetic change

A genetic change is a permanent alteration in the DNA informational content of an organism. The alteration in informational content may imply changes in the nucleotide sequence of the organism's genome or a structural change that brings about modifications in the normal way genes are arranged and/or expressed. Genetic changes are, by definition, inheritable.

Answer and Explanation: 1

The correct answer to this question is "e. Binary fission". Mutation, along with all forms of horizontal gene transfer (transformation, conjugation, and transduction) and transposition are the only ways the genome of a bacteria can change in a permanent, heritable manner. Binary fission, on the contrary, refers to the way bacteria divide: that is, by giving origin to two daughter cells in a process that involves DNA replication and segregation simultaneously, immediately followed by cytoplasm division.
