6. A strain of bacteria living in a hospital is found to have a plasmid containing two genes: one forsex pilus construction, and one for tetracycline resistance. If these bacteria were to undergoconjugation with bacteria lacking this plasmid, and thereby transferred the plasmid to the otherbacteria, the most likely result would be:A. a genetically identical clone of bacteria containing the same plasmid.B. a possible spread of tetracycline resistance to other bacteria in the hospital.C. the subsequent loss of tetracycline resistance in the initially resistant strain.D. production of endospores in the bacterial progeny.E. temporary tetraploidy of the conjugating bacteria.
Question
- A strain of bacteria living in a hospital is found to have a plasmid containing two genes: one forsex pilus construction, and one for tetracycline resistance. If these bacteria were to undergoconjugation with bacteria lacking this plasmid, and thereby transferred the plasmid to the otherbacteria, the most likely result would be:A. a genetically identical clone of bacteria containing the same plasmid.B. a possible spread of tetracycline resistance to other bacteria in the hospital.C. the subsequent loss of tetracycline resistance in the initially resistant strain.D. production of endospores in the bacterial progeny.E. temporary tetraploidy of the conjugating bacteria.
Solution
The most likely result of the scenario described would be B. a possible spread of tetracycline resistance to other bacteria in the hospital.
Here's why:
-
Conjugation is a process in bacteria where one bacterium transfers its genetic material to another bacterium. In this case, the bacteria in the hospital have a plasmid (a small, circular piece of DNA) that contains two genes: one for sex pilus construction and one for tetracycline resistance.
-
The sex pilus is a structure that allows bacteria to connect and transfer genetic material. The gene for tetracycline resistance would allow the bacteria to survive in the presence of the antibiotic tetracycline.
-
If these bacteria were to undergo conjugation with bacteria that do not have this plasmid, they could potentially transfer the plasmid and its associated genes to the other bacteria.
-
This would mean that the other bacteria would now also have the gene for tetracycline resistance, allowing them to survive in the presence of the antibiotic. This could potentially lead to a spread of tetracycline resistance among other bacteria in the hospital.
Therefore, the most likely result of this scenario would be a possible spread of tetracycline resistance to other bacteria in the hospital.
