Question

Determine the significance of plasmids for bacteria. A.They help in meiosis and in the manupulation of the plasmids of their host organisms. B. They help in meiosis and in the manupulation of their genome with the gene of their requierment. C.They help in reproduction , antibiotic resistance, virulence and competition with other bacteria

Answer 1

The correct answer is C.They help in reproduction , antibiotic resistance, virulence and competition with other bacteria

Step-by-step explanation:

Plasmids are the small, single circular DNA molecule that is different from the chromosomal DNA of bacteria. These plasmids can replicate independently from the chromosomal DNA. Plasmids are naturally found in bacteria.

These plasmids contain some extra genes like antibiotic-resistant genes that provide bacteria an advantage in a competition over bacteria that do not have plasmid with antibiotic-resistant genes because when antibiotic is used against these bacteria the bacteria having antibiotic-resistant gene will survive.

Plasmid also code for virulence factors in bacteria like toxins, adhesin proteins, etc. Therefore the right answer is C.

Answer 2

I think the correct answer from the choices listed above is option C. Plasmids are small DNA molecules within a cell that are important for bacteria because they help in reproduction , antibiotic resistance, virulence and competition with other bacteria.
