Which of the following is NOT an advantage of introducing a plasmid into a bacterial strain?

A) Antibiotic resistance
B) Reporter gene expression
C) Transformation efficiency
D) Restriction enzyme recognition

Answer :

Final answer:

The gene encoding enzymes for glycolysis is not likely to be found on a plasmid; such genes are usually located on the bacterial chromosome.

Explanation:

The gene that is NOT likely to be encoded on a plasmid is C) gene encoding enzymes for glycolysis. Plasmids are small, circular DNA molecules within bacteria that are separate from the bacterial chromosome and can replicate independently. They often carry genes that confer beneficial traits such as antibiotic resistance or the ability to metabolize unusual substrates, which can be advantageous in certain environments.

However, genes for essential metabolic pathways like glycolysis are typically located on the bacterial chromosome, not plasmids, because they are essential for the survival and normal operations of the cell under all growth conditions.
