Question

How do we know that genes exist in bacteria and bacteriophages?

A. Genetic variants of bacteria were discovered by their dependence on certain media. Mutant bacteriophages were discovered by variations in their plaque morphology and host range. B. Genetic variants of bacteria were discovered by their resistance to infection by bacteriophage and their dependence on certain media. Mutant bacteriophages were discovered by host range. C. Genetic variants of bacteria were discovered by their resistance to infection by bacteriophage and their dependence on certain media. Mutant bacteriophages were discovered by variations in their plaque morphology and host range. D. Genetic variants of bacteria were discovered by their resistance to infection and their dependence on certain media. Bacteriophages were discovered by variations in their plaque morphology and host range.

Explanation / Answer

Answer:

Explanation:

Bacteria will have an extrachromosomal DNA, which called as plasmid. The plasmid helps in resistance to infection by phage viruse.

C. Genetic variants of bacteria were discovered by their resistance to infection by bacteriophage and their dependence on certain media. Mutant bacteriophages were discovered by variations in their plaque morphology and host range.
