Consider that two bacteria produced by binary fission do not have the same phenotype. The most likely explanation is that

A they are genetically different

B the cells are not undergoing transcription and translation

C the cells have different cell wall compositions

D they have different gene expression

The most likely explanation is the cells have different cell wall compositions when two bacteria produced by binary fission do not have the same phenotype.

Answer: Option C

Explanation:

Bacteria's reproduce asexually. Binary fission is a process of propagation found in bacteria. In bacteria it is done by the cell enlarging and then the cell dividing into two.

The cell copies it's DNA into two and then move sit to the end of the cell and then forms a new cell wall. It is the formation of new bacteria where the old organism is replaced with the new one which are genetically identical.
